Gearman server stucks in case of death of worker about gearmanmanager HOT 8 CLOSED

This problem also reproduced on the last version of Gearman (1.1.11)

from gearmanmanager.

Hello
We have found the reason of this problem.
It is appeared when we set timeouts in config.ini
this timeout is used in worker->addFunction

When we remove this parameter the problem was solved.
So I think it is the problem in Gearman or pecl but not in GearmanManager

We experiencing the same problem with gearman server. Sometimes it just stucks.
But we thought it's gearman-server or pecl-gearman issue.

Will try to delete timeouts from config.ini
Thanks for sharing info, such problems are really hard to inspect.

Also experiencing the same problem and using gear manager. I was using a timeout of 12 hours, and then recently changed to 2 hours (hoping to eleviate the problem) but it actually made it worse. So your explanation of the timeouts causing the problem would make sense. I have removed the timeouts today and am hoping it will solve the problems. Thanks for sharing the info!

I'm not using any timeouts, but my workers are now stuck. :-/

@simoncpu The others are talking about gearmand getting stuck, not workers I believe. What do you mean by your workers are now stuck?

From what I can tell, the pecl-gearman library does not have good timeout support for detecting connection/read/write timeouts to the gearmand. I have some better timeout detection in NetGearman that I need to push to Github that works much better.

Hi @brianlmoon! I can no longer experience the problem. I modified my code to be more robust, and I set a timeout of 30sec in the config. My previous code was hacky and used funky exec() calls. I think it caused the PHP workers to timeout (it often creates zombies, if run without gearman, but the OS just reaps them eventually). I'm sorry, but I can no longer provide any details. GearmanManager is now working smoothly on our setup. =)

@AlexeyOrlenko
Thank you very much! I've been debugging this for a looong time now and it seems to work better (so far) after commenting out the "timeout" setting in config.ini.

@brianlmoon
I would strongly recommend that you put this in a comment in config.ini, as it will certainly save some other poor soul 2-3 days of wasted debugging
