loaded. The code to raise this warning was already present but it was not being shown in many cases (when it actually should). It now looks like this, if you run ./unrealircd start and previously crashed AND have any 3rd party mods loaded: The IRCd has been started now (and is running), but it did crash 1 seconds ago. Crash report generated in: /home/ircd/unrealircd/tmp/crash.report.core.1621838267.txt ** IMPORTANT ** Your UnrealIRCd crashed and you have 3rd party modules loaded (modules created by someone other than the UnrealIRCd team). If you installed new 3rd party module(s) in the past few weeks we suggest to unload these modules and see if the crash issue dissapears. If so, that module is probably to blame. If you keep crashing without any 3rd party modules loaded then please do report it to the UnrealIRCd team. The reason we ask you to do this is because MORE THAN 95% OF ALL CRASH ISSUES ARE CAUSED BY 3RD PARTY MODULES and not by an UnrealIRCd bug. Shall I send a crash report to the UnrealIRCd developers? NOTE: If the crash is caused by a 3rd party module then UnrealIRCd devs can't fix that.
