Hi, I have migrated my SER proxy from Linux servers to Sun Solaris 10 (sparc 64 bit). Same SER version (0.9.3) and config file work perfectly fine under Linux and now its crashing. Every time SER needs to fork of a new branch (append_branch();) it core dumps. any idea why this would be happening? thanks fil here is the portion of ser.cfg which is crashing: failure_route[4] { log (1, "**************** FAILURE_ROUTE[4] CALLING VOICEMAIL\n"); # forward to voicemail now if (isflagset(4)){ rewritehostport("192.168.0.5:5060"); append_branch(); route(1); }; } here is the the SER startup with debuging set: 0(17715) failure routing table 4: 0(17715) log( 0(17715) 1 0(17715) , "**************** FAILURE_ROUTE[4] CALLING VOICEMAIL " 0(17715) ); 0(17715) if ( 0(17715) isflagset( 0(17715) 4 0(17715) ); 0(17715) isflagset( 0(17715) 4 0(17715) ); 0(17715) ) { 0(17715) sethostport( 0(17715) "192.168.0.5:5060" 0(17715) ); 0(17715) append_branch( 0(17715) Segmentation fault here is the output of gdb run: gdb -c /var/core/core.ser.17722 /usr/local/sbin/ser GNU gdb 6.3 Copyright 2004 Free Software Foundation, Inc.
