If this happens consistently for you would you mind trying the following:
- Start btop with
gdb -ex run btopyou will se some gdb output next to the clock, just ignore that. - When btop hangs, press CTRL+C , if gdb prompts about more information just press enter.
- Press CTRL+L to clear the screen
- Type command
btto get the backtrace - Post the backtrace here
That way we could maybe figure out were it gets stuck.

It's been stable for the last 2 days so that was the issue, thanks

For best result make distclean and make OPTFLAGS="-O0 -g" to get as much debugging info as possible with gdb.
And then when stalled, try to get as much of the current stack as possible to find out exactly what's going wrong.
I'm in no way an expert in the workings of gdb so can't say for sure, but logging "live" gdb debugging output to a file would probably be a bit tricky (and quickly get large) with the amount of data it likely would generate.

Just a dumb suggestion: spdlog + rotating file logger e.g. max 10MB. Will try out installing from the repo as you suggest.

Last one didn't work I just noticed. But I've replaced the clock_nanosleep() trigger with cpu pause instructions in the loop causing the problem in the latest commits.
If you need static binaries you can get them from the continuous build workflow

I believe I might have fixed it in latest commit. Still stable in my test setup so far.

I've removed the use of async threads in the secondary thread which I believe might have been the cause of the issue, and they weren't really serving any use. Probably reduced cpu usage a bit by removing them.
So please make clean and build with latest commit or run the latest static build to see if it's still stalling for you.

@vaygr
It's possible there was two seperate issues causing stalls and the removal of the async threads fixed on of them.
But there might still be the possibility of a stall from the ifstream issue in the build you are running.
Both are fixed in latest commit that have been running stable in my test setup for over 7 hours now.
Will wait for at least 24 hours stable before pushing a new release with the current fixes.
After that we can hopefully close this issue for good :)

Thanks @aristocratos. After 2 weeks of uptime of 1.2.0 I think it's safe to say it's fully resolved.

I managed to replicate it and found it had stalled on a atomic wait operation, not sure why. But I've changed some things in latest commit.
If you compiled yourself you can try pulling and recompiling.
Otherwise you're gonna have to wait a while until I've confirmed my fix worked. Want to have it running for at least 24 hours to make sure.

Thanks! I'm still running with gdb in hope I can replicate but it's working as expected. I think I'll just run with gdb until a new release :).

I still see this bug when I leave btop running for a long time. The backtrace shows it failing at the atomic_wait at the top of the run function.

I haven't done a make clean recently so I'll do that and then comment back if it crashes again

That's probably it, should be impossible for atomic_wait() to stall after the changes in v1.0.11.

Same issue for me. Using pre-built 1.0.14 on Manjaro.
After running for 2-3 hours went into an infinite loop with this:

Need some more information:
- Does it stall with 100% cpu usage on one core like before?
- Does it happen without any user interaction, no resizing, wake from sleep etc.?
- What time do you have set on the update timer
update_ms? - Does CTRL+c fail?
from btop.
jmakov
commented on June 16, 2024
- yes
- yes, I just notice nothing is happening and open htop in another window where I see btop using 100% of 1 core
- default settings, I just run

Any more debugging info you can give me would be very helpful. I'm having a hard time reproducing the issue, so really have no idea of the chain of events leading up to the stall right now.

I experience the same issues:
- btop++ version:
1.0.14 - Architecture:
x86_64 - Platform:
Debian GNU/Linux 10 (buster) - Linux Kernel:
4.19.0-17-amd64 - Terminal used:
byobu (byobu version 5.112; tmux 2.8) via PuTTY (p0.67-t029)
In the options menu of btop++, I set the log level to DEBUG. Yet, the only output I received was the following:
2021/10/11 (19:26:30) | ===> btop++ v.1.0.14

About an hour later it hang. At 20:23:36.
- Does it stall with 100% cpu usage on one core like before?
- Unfortunately I pressed CTRL+C too early, so I can't tell wether it got stuck with 100% cpu load. But at least Zabbix monitoring doesn't seem to suggest that there was an extra load put on the CPU. Regarding the other three questions:
- Does it happen without any user interaction, no resizing, wake from sleep etc.?
- Yes, I was not doing anything on the server at that time.
- What time do you have set on the update timer update_ms?
- 1500ms
- Does CTRL+c fail?
- Well, it used to fail and I had to kill it. This time I ran
gdb -ex run btopand so gdb took action when I pressed CTRL+C.
- Well, it used to fail and I had to kill it. This time I ran
The gdb stack trace is identical to the one posted by @jmakov earlier:

So I assume, that Debian Buster's g++ compiler doesn't support this standard. 😕 Could you maybe provide a stically linked debug build? Maybe with even more debug routines all around that clock_nanosleep (), so I can provide you with more information?

There are some fixes in v1.0.15 that if it doesn't fix the issue, should at least not stall (but maybe crash instead).
However if it crashes instead, we should at least gain some useful information about what's going wrong :)

Still stalls, but at least exits out with a error message now.
Noticed I missed some stuff from @tomterl debug log in #83
It looks like it might possibly be stalling on ifstreams ignore in Proc::collect()
Added some more ifstream error checks and added an attempt at restarting the secondary thread in case of a stall.
Please try with latest commit or new static binaries
Edit: Note that if the thread restart is successful in case of a stall it will only print out a message to the logfile. So please check your btop.log file after running for a while too see if the underlying issue is still present. Or set a break point in gdb at line 544 if running a debug build.

Seems like the issue is back after I upgraded to 1.1.0. However, this time 100% CPU usage is intermittent.
The first time btop froze around 10:30am, and 100% CPU usage spiked only at about 3pm same day.
Right now it froze at 6:30am with the following strace context:
ioctl(0, FIONREAD, [0]) = 0
clock_nanosleep(CLOCK_REALTIME, 0, {tv_sec=0, tv_nsec=10000000}, 0x7ffe210d4d30) = 0
ioctl(0, FIONREAD, [0]) = 0
clock_nanosleep(CLOCK_REALTIME, 0, {tv_sec=0, tv_nsec=10000000}, 0x7ffe210d4d30) = 0
ioctl(0, FIONREAD, [0]) = 0

aristocratos
commented on June 16, 2024
@vaygr
I've had a build running 30+ days without encountering any issues.
The ioctl(0, FIONREAD, [0]) could indicate that this is happening when trying to check the state of standard input and for some reason getting stuck there. The only possibility for stalling there (to my knowledge) would be if the number of characters in standard input for some reason was below zero, which shouldn't be possible.
But could maybe indicate a issue on your system (hardware or software).
Added a fix in latest commit so the suspected loop will break if the value is 0 or below, and we can see if that's the cause of the stall. But guess it will take some time before we know if it worked considering how rare it seems to be.
But I don't have any way to for sure figure out what's happening (or how to fix it) without a proper backtrace leading up to the stall.

btop version: 1.3.2
sys-process/btop-1.3.2::gentoo
This time for sure I didn't update anything of the system. But I did install one new package: app-misc/jq-1.7.1 (Description: A lightweight and flexible command-line JSON processor)
Hope this helps? :)
I haven't killed it yet, let me know if you need me to try something else on it?
Ah looks like i forgot this even existed, anyway here's what I've found:

Anyway here's the screen, frozen:
so finally pressing q after all this time, did insta quit it, with no high cpu usage or anything.

I'm by far no expert (I mean look at this to see how noobish I r), but i took a look at the code and the handling of atomics seems wrong in some places, like you have:
- if (Global::quitting) return;
- Global::quitting = true;instead of something like compare_exchange:
+ bool expected = false;
+ if (!Global::quitting.compare_exchange_strong(expected, true)) {
+ //return of false ^ means the exchange wasn't made
+ // because expected value wasn't false
+ assert_eq(true,expected);//aka the prev. value was 'true'
+ return; // quitting was already true
+ } else {
+ assert_eq(false,expected);//prev. value
+ }But anyway, the problem in my ante-prev comment with 100% cpu usage on quit, happens if the runner thread got restarted at least once(I emulate this in the patch below by using activated_once atomic), and thus to make it quit instead of use 100% CPU forever, a quick hack is adding thread_trigger(); right before the last statement stopping = false; in the Runner::stop(), but I'm not sure if fixing the other atomics' usage is also needed as well, too ( :D ) and whether a sleep_ms() is needed or not after the pthread_cancel since it's doing things async... so I've left more things for you to consider.
Anyway this is what I did as mentioned:
