Sometimes I got crash like this:
PHP Code:

I would like to thank Joonas from the srcds_linux mailing list for identifying what "Alarm clock" is. I went to go search for it on google (srcds SIGALRM) and I found this: http://noteand.blog.eonet.jp/weblog/2009...-da30.html

Quote:
"* The linux dedicated server supports a watchdog timer functionality,
which is enabled by default. The intent of this timer is to make
anything which hangs the server, either due to unknown bugs or
misconfiguration, cause an abort, so that the server may restart or
be debugged. In the case of a forked server, this will cause a new
subprocess to start to replace the crashed one. On a non-forked
server, this can be used in conjunction with an auto-restart script
in order to increase server availability. If you see your server
dying with SIGALRM (signal 14), it means that this has triggered
because of either a server frame taking longer than 5 seconds of
wall time, or a map load taking too long. If this code causes
trouble for you, it can be disabled via giving the "-nowatchdog"
option on the command line."

I put the -nowatchdog switch in srcds_run and switching to something like realism, mutation, etc. from the lobby with sv_search_key WORKS now! I think reliability might be an issue, so now I have to test out how much I can push out of my old linux box.

Thanks a lot for all your help, guys!

Not sure if it's better to start a new thread or tack on an existing thread for the same topic that's almost a decade old, but we had this issue last night with 3 (out of our 11) servers -tokyo, singapore, and australia locations.

We have 11 servers total, hosted on the same OS (Ubuntu 18.04.5 LTS) and provider (Vultr). Once per day each server rsyncs server updates from a github repo we keep up-to-date. So the servers that where working had the same exact config as the servers that where throwing this error, except some files mostly related to gamedata stuff SM keeps updated ( line 41-57 here )

The servers throwing the error would start up correctly and around 30 seconds later would come up with the Alarm clock message, then reboot.
Code:
VAC secure mode is activated.
L 09/07/2021 - 02:58:11: [GasConfig_v2.smx] [GasConfig] Connected to the database successfully.
ConVarRef mat_hdr_manual_tonemap_rate doesn't point to an existing ConVar
 atrium map script
L 09/07/2021 - 02:58:12: [OnLogAction_To_DB.smx] Connected to the database successfully.
L 09/07/2021 - 02:58:12: [SurvivalRecorder.smx] Connected to the database successfully.
L 09/07/2021 - 02:58:14: [SurvivalRecorder.smx] Database tables initialized successfully
Alarm clock
Add "-debug" to the /root/L4D2/srcds_run command line to generate a debug.log to help with solving this problem
Tue Sep  7 03:00:04 UTC 2021: Server restart in 10 seconds
Accelerator didn't pick anything up so I tried the default "-debug" launch setting which ended up being useless:
Code:
CRASH: Tue Sep  7 04:27:42 UTC 2021
Start Line: ./srcds_linux -game left4dead2 -tickrate 30 -ip 45.32.29.94 -port 27015 +map c1m4_atrium +mp_gamemode survival +tv_enable 1 -debug
End of Source crash report
Hostname wasn't showing up either except for ~ 1 second after launch (it gets relaunched automatically from a running shell script) - https://youtu.be/hzM6Wo-ZgaE

tried -nowatchdog and I was able to join one server that ended up crashing soon after. Tried loading the same server and it crashed while loading from lobby but generated a .dmp crash log file:
https://www.dropbox.com/s/mlc900tl72...45_28.dmp?dl=0

Also tried to diffcheck the console output from bootup to "Database tables initialized successfully" for a working server and one erroring out; no major differences.

Only our Australia server is still having the issue but I don't have FTP access as someone else is sponsoring that location.

Made this post in-case I luck out and someone might've had this issue before
