Hi Andrei,
Hope you are fine. Do you have any update on our crash ? Is there anything we can do to find the segmentation fault cause, maybe as a well-known bug, without bothering you ?
There are lots of changes between 0.9.5-pre and the latest 0.9.x version. You should try updating to the latest code on the rel_0_9_0 branch and see if you run into this problem again. To get the latest 0.9.x code either get the latest snapshot from http://ftp.iptel.org/pub/ser/daily-snapshots/stable/ , use cvs to get the rel_0_9_0 branch (CVSROOT=:pserver:anonymous@cvs.berlios.de:/cvsroot/ser ; export CVSROOT ; cvs co -r rel_0_9_0 sip_router ), or use git and the ser repository (see http://sip-router.org/wiki/git/ser-repository).
Here's a short changelog for tm, between 0.9.5 and 0.9.7+ (git log --oneline v_0_9_5..origin/rel_0_9_0 modules/tm): - tm: fix delete_cell() when the transaction is referenced - variable timer fix: variable timers (avps) won't be exteneded anymore - fix for free_rdata_list() which used to access the "next" pointer af - deadlock when t_relay-ing a message from the failure_route fixed (e2e - added sems specific patch. This patch is present in the ser version ship - added diversion and rpid header cloning -bug fix: tm insert_timer used to eat too much cpu, decreasing dramatic - fixed misplaced set_avp list, courtesy of cesc.santa@gmail.com - int2reverse_hex/reverse_hex2int fixes (tm with large "labels" was aff - fix of local ACK matching provided by cesc.santa@gmail.com - avp race condition fix (backported from HEAD) - CANCEL terminates retransmission timers properly (backported)

Please find the requested information in attached.
I'm aware of the need for an update. It's in the list of tasks to be done, however, the priority is to troubleshoot the problem and maybe find a workaround.

Hi Andrei,
Thanks for your reply.
I use ser 0.9.5-pre4.
I don't really understand the bug you have identify, where can I find a description ?
Sorry, I was wrong (that bug was in RR and appears only in newer code).
Could you run gdb on the core again , type "frame 0" and then send me the output of the following commands:
print p_cell print p_msg print p_msg->buf print p_cell->uas.local_totag.len print p_cell->uas.local_totag.s print p_msg->to print p_msg->to->parsed print *((struct to_body*)(p_msg->to->parsed)) print ((struct to_body*)(p_msg->to->parsed))->tag_value.len print ((struct to_body*)(p_msg->to->parsed))->tag_value.s
Andrei P.S.: you could try also upgrading to ser 2.0, 2.1 or sip-router.
Regards,
Adrien

Hi Klaus,
Thanks.
I put the output of gdb in attached.
I hope someone can decrypt this. Thank you.
If you are using ser 2.1/latest cvs or sip-router then just update to the latest cvs or git. It's a known fixed bug (sip router git 6fcd5e or ser 2.1 commit starting with "rr: fix from header access").
If you are using another version then tell me which one (ser -V) and I'll fix it.
Andrei
