sleepingserver crashes after Minecraft server goes to sleep. about mcsleepingserverstarter HOT 11 CLOSED

Hi !
You don't see any relevant information in minecraft's log or SleepingServer's log ? Can you post them ?

from mcsleepingserverstarter.

I'm trying to reproduce the crash but didn't manage to reproduce for now.
There is no clear indication of what's wrong in the logs.
Do you have the web-server enabled ? (from the logs, it doesn't seem to be enabled.)

from mcsleepingserverstarter.

Yeah sure! I will take a look later tonight

oh yes sorry,
The Minecraft log looks normal to me. take a look yourself: (btw logs are all the same.)

I did take a better look at the sleeperserver's logs and it seems to be inconsistent where it crashes. also, more than I originally thought. : sleeperserver logs
one thing to point out, at some point a ping bot found my server and constantly was pinging the server.

sadly I'm not finding in the log anything directly pointing to what the problem could be.

SO the bug finaly clearly accured on one of my servers:
It seems like if 2 players try to join at the same time while sleeperserver is trying to startup the minecraft server, thats when things go wrong.

The bug is a bit stubborn. I only had seen it occur when two or more players different try to join at the same time.

There is no clear indication of what's wrong in the logs.

I've read the sleeper-server log a little better. Here are my thoughts on what could be happening. Grab a small drink and strap in. ;-)

From lines 38 to 45:
Two players join a few seconds after each other.

Player 1: Triggers the server startup and receives best regards message
Player 2: starts the server up too but can't because player 1 already did it. Also still receives best regards message. (triggering the bug later on)
** Sleeper server stops and Minecraft server starts up after 5 min shuts down**

From line 56
I think here is where the bug occurs.
First, the sleeper server wakes up. Then wakes the Minecraft server immediately up without a timeout and anyone asking it to startup.
It could be happening because the startup flag of player 2 is still set.

After the Minecraft server shuts down, sleeper-server somehow ain't able to wake up/startup and crashes.

Do you have the webserver enabled? (from the logs, it doesn't seem to be enabled.)

Nope, I don't have it enabled.

I hope this makes it at least a little better trying to understand what's happening.

edit: added serversleeper log

Hi!

I've got a quick update on how it's going.
Today I went bug hunting with my friends. Now I'm sure it only occurs when two or more players join somewhat simultaneously.

After the previous Minecraft server has shut down, the sleeperserver immediately stops and starts up the Minecraft server again. It does this until some event causes it to crash.

Here below is the serversleeper log, with the bit where serversleeper crashes.

PS: Please look at the time between events, some things doesn't make any sense to me

Bump

Did you try with the binary version ? 1.18.1 ?
I still cannot reproduce, so it's not easy to debug.

EDIT: Ok, I found something. I will try to fix it.

from mcsleepingserverstarter.

I made a new release : https://github.com/vincss/mcsleepingserverstarter/releases
Can you give it a try ?

from mcsleepingserverstarter.

hey man! sorry for taking so long to reply but it seems like the bug is fixed!
If it happens again I'll say it!
