High-Populated Modded Servers are Crashing on Player Spawn Events
Reviewed, NormalPublic

Description

I've been keeping up with modded server crashes for the past month or two, and I've noticed most server RPT's show a crash on either a player respawn who just died or a player logging in when server's seem to get above 40+ players. It happens at random when above 40+ players, but %99 are consistent with the player spawn event being the last thing inputted at a crash.

Looks like my server crash issue is the exact same as what you're reporting : https://feedback.bistudio.com/T149787 (you won't see it's private because of the logs, but I've already sent 100+ full logs and reported it a month ago)

In my case it also crashes right after the <LOAD EXISTING CHAR>: log, but it shows my mod as the issue in the .RPT, what does shows yours ? Also you should send RPTs + MDMPs at least so they can look at it.

I'll also add that in my cases, sometimes the server crashes even when it's been started recently, no need to wait 1-2 hours, it's really random. Same for the playercount, sometimes it crashes with 9 players online, sometime it won't crash with 40 players.

Also, for referance, end of RPT in my cases says :

Can provide full files, plus hundreds of more from my other servers, weve been crashing consitently since 1.07 has dropped.
One thing that seems consistent throughout all of these is that it always seems to happen as a player loads in, either from the queue or from respawn.

Hello CashewSan.
If your server experiences any crashes, please create a private ticket containing the rpt / mdmp files from the server. Also, if you are running any mods, if it is possible to test this without them or possibly narrow this down to the specific mods you are using, it would help us as well.
Regards,
Geez
