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(a)gmail.com - int2reverse_hex/reverse_hex2int fixes (tm with large "labels" was aff - fix of local ACK matching provided by cesc.santa(a)gmail.com - avp race condition fix (backported from HEAD) - CANCEL terminates retransmission timers properly (backported) Andrei > > Le vendredi 14 ao??t 2009 ?? 17:03 +0200, inge a ??crit : > > Please find the requested information in attached. > > > > I'm aware of the need for an update.
