[OpenSIPS-Users] core generated by opensips

Hello,

Can you replicate the crash on demand, or does it happen randomly ?
Would you be able to provide access to a server containing the core file 
and the OpenSIPS binary, in order to speed-up the debugging process ( 
avoid the ping pong on the mailing list ) ?

Regards,
