But why such crond hangs? It needs kill -9.

Of course we are using: ./unrealircd start Also using ~/unrealircd croncheck in crontab and found that after the crash there is crond process hanging with postdrop trying to send some email. Anyway, not sure how does UnrealIRCd "offers me" to send anything, since I am not always logged on ;)

Many thanks Gottem, got it now with "unrealircd backtrace". Is such report different than the one gdb would create directly?

I've opened the bug report, hopefully Syszop will solve this issue.

Right, but the crash happens every 2 days, so I need to launch it in background and log off somehow?

"unrealircd backtrace" doesn't seem to work, it just prints out "Usage: unrealircd [-f <config>] [-h <servername>] [-p <port>] [-x <loglevel>] [-t] [-F]"

The server was full, I wasn't around. Now it happened again when I was there, nobody did anything special: kernel: unrealircd[41776]: segfault at 4841e349 ip 000000004841e349 sp 00007ffe44191158 error 14 in 8EF21E.jointhrottle.so[7ff2ec4c3000+2000] Two days ago: kernel: unrealircd[11298]: segfault a...

Yes, using one custom module from Syzop.

Is it possible to dump core or find the cause different way next time it happens?

Awesome, many thanks Gottem!

I've added module and reloaded IRC. Is it possible that it has something to do with crash after 2 hours:

kernel: unrealircd[11298]: segfault at 9c48f0 ip 00000000009c48f0 sp 00007ffdc4a09f58 error 15

It was stable 3 days before this.

After upgrade from 3.2 to 4.0.6 seeing plenty of "WARNING: Slow I/O engine or high load" messages. Anybody have an idea what is the cause or how to find it? Having dedicated server for IRC only. Load average: 0.69, 0.72, 0.67. [Fri Sep 9 18:31:38 2016] - WARNING: Slow I/O engine or high lo...

It would be of great help if someone could port this module (attached) to Unreal 4. Many thanks in advance.
