Re: [Kamailio-Users] kamailio crashes during connection attempt

Hello, might be a buffer overflow somewhere else. I will send you some instructions to compile with memory debug one. Meanwhile, this seems to be a particular case (has to be found and fixed anyhow), the SUBSCRIBE is looping. Is voice.djuk.ee a local domain (matching the 'myself' condition)? If is local domain and not in dns then add: alias=voice.djuk.ee Cheers, Daniel On 2/8/10 10:14 PM, Dmitri wrote: > Hello, > > Updated gdb output in attached file. > > BR, > Dmitri > > 08.02.2010 22:51, Daniel-Constantin Mierla пишет: >> Hello, >> >> once you are in gdb, run 'bt' to get the backtrace.
