I am setting the dialog flag for any incoming call..... Whenever a load test is running, this error occurs. I am not sure if it is reproduceable, or not. But I think it should be, because in worst case (during a load test over night) this error was indicated in a period of 1-2 minutes. But I've found this error only yesterday, because the server was down (as a result of this error....).

The daemon (kamailio_3.0.4+lenny1_i386.deb) is running on a virtual machine (ESX) with OS Debian Lenny.

How can I find / deliver additional info to this error / fault for analyzation?

Hi Klaus, try to get hold of a core dump, and analyse it. More informations e.g. here: http://www.kamailio.org/dokuwiki/doku.php/troubleshooting:corefiles The backtrace that you get will help a lot in debugging and also fixing the issue. Cheers, Henning
