 It would be definately more help if you would follow the instructions on the Report Issue page to get a backtrace and post that here. You may also run ./unreal backtrace

Are you using any 3rd party modules? (anything besides commands.so and cloak.so)
If so, which?

Sorry, I forgot to write the 3rd party used modules. Here they are:

m_ircops, cmdflood, hideserver, identonly, m_clones, netadmins, noctcp, m_spy, vhosts, randquote, operjoin, hostnameonly, m_staff, commandsno, m_chgwhois, regexban, adwords.

I forgot to reply...
What I suggest is running without all those 3rd party modules and see if you crash. If you then still crash, we can be sure it's a problem in UnrealIRCd and not in the modules.
(that is, I'm assuming you did not modify any unrealircd code)

So if that happens again without the 3rd party mods and no modifications, let us know.

It looks like heap corruption anyway, which is hard to trace down.
