Hello Daniel,
yes, with the production config I still get a core, not with the testing config, though. The last line in log with testing config is: Dec 4 13:28:06 lvm-centos-kamailio1 /sbin/kamailio[8045]: ERROR: <core> [action.c:1572]: run_actions(): WARNING: too many recursive routing table lookups (101) giving up! Dec 4 13:28:06 lvm-centos-kamailio1 /sbin/kamailio[8045]: WARNING: <core> [receive.c:214]: receive_msg(): WARNING: receive_msg: error while trying script But I have 2 cores, each 52M in size from production config. I will bzip them and send them via email. Kind regards, Timo Klecker Von: Daniel-Constantin Mierla [mailto:mico...@gmail.com] Gesendet: Donnerstag, 4.

The easiest to troubleshoot is to get the backtrace from the core with gdb. Setting up a testbed requires more resources, not trivial when out of the office.

(Please change modules path according to installation) The attached Kamailio configuration is a (very) simplified configuration we are running in production. 10.10.207.20 is a server running the attached Kamailio configuration. 10.10.210.71 is a server running sipsak, sending the attached invite. sipsak -s sip:10.10.207.20:5060 -f invite.txt The crash seems to occur due to a missing exit of the configuration loop. So to get rid of the crash I would break the loop if $rU equals null after modification in MODIFY_NUMBER. The issue now simplifies to: You cannot empty $rU when a password is set, because the URI becomes invalid due to missing @: bad uri <sip::pass10.10.207.20> <sip::pass10.10.207.20> Dec 4 13:27:50 /sbin/kamailio[8043]: NOTICE: <script>: ru initial: sip:123456:pass@10.10.207.20 Dec 4 13:27:50 /sbin/kamailio[8043]: ERROR: pv [pv_core.c:304]: pv_get_ruri_attr(): failed to parse the R-URI Dec 4 13:27:50 /sbin/kamailio[8043]: NOTICE: <script>: rU set to: <null> Dec 4 13:27:50 /sbin/kamailio[8043]: ERROR: pv [pv_core.c:236]: pv_get_ruri(): failed to parse the R-URI Dec 4 13:27:50 /sbin/kamailio[8043]: NOTICE: <script>: ru set to: <null> Dec 4 13:27:50 /sbin/kamailio[8043]: ERROR: pv [pv_core.c:304]: pv_get_ruri_attr(): failed to parse the R-URI Dec 4 13:27:50 /sbin/kamailio[8043]: ERROR: <core> [action.c:805]: do_action(): ERROR: do_action: bad uri <sip::pass10.10.207.20> <sip::pass10.10.207.20>, dropping packet Dec 4 13:27:50 /sbin/kamailio[8043]: ERROR: <core> [action.c:1553]: do_action(): run action error at: :0 Dec 4 13:27:50 /sbin/kamailio[8043]: ERROR: pv [pv_core.c:2080]: pv_set_ruri_user(): do action failed Dec 4 13:27:50 /sbin/kamailio[8043]: ERROR: <core> [lvalue.c:363]: lval_pvar_assign(): setting pvar failed Dec 4 13:27:50 /sbin/kamailio[8043]: ERROR: <core> [lvalue.c:416]: lval_assign(): assignment failed at pos: (49,11-49,21) This loops: Dec 4 13:27:50 /sbin/kamailio[8043]: ERROR: pv [pv_core.c:304]: pv_get_ruri_attr(): failed to parse the R-URI Dec 4 13:27:50 /sbin/kamailio[8043]: NOTICE: <script>: rU set to: <null> Dec 4 13:27:50 /sbin/kamailio[8043]: ERROR: pv [pv_core.c:236]: pv_get_ruri(): failed to parse the R-URI Dec 4 13:27:50 /sbin/kamailio[8043]: NOTICE: <script>: ru set to: <null> Dec 4 13:27:50 /sbin/kamailio[8043]: ERROR: pv [pv_core.c:304]: pv_get_ruri_attr(): failed to parse the R-URI Dec 4 13:27:50 /sbin/kamailio[8043]: ERROR: pv [pv_core.c:304]: pv_get_ruri_attr(): failed to parse the R-URI Dec 4 13:27:50 /sbin/kamailio[8043]: ERROR: <core> [lvalue.c:356]: lval_pvar_assign(): non existing right pvar Dec 4 13:27:50 /sbin/kamailio[8043]: ERROR: <core> [action.c:805]: do_action(): ERROR: do_action: bad uri <sip::pass10.10.207.20> <sip::pass10.10.207.20>, dropping packet Dec 4 13:27:50 /sbin/kamailio[8043]: ERROR: <core> [action.c:1553]: do_action(): run action error at: :0 Dec 4 13:27:50 /sbin/kamailio[8043]: ERROR: pv [pv_core.c:2059]: pv_set_ruri_user(): do action failed) Dec 4 13:27:50 /sbin/kamailio[8043]: ERROR: <core> [lvalue.c:363]: lval_pvar_assign(): setting pvar failed Dec 4 13:27:50 /sbin/kamailio[8043]: ERROR: <core> [lvalue.c:416]: lval_assign(): assignment failed at pos: (46,11-46,26) Kind regards Timo Klecker Von: sr-users-boun...@lists.sip-router.org [mailto:sr-users-boun...@lists.sip-router.org] Im Auftrag von Daniel-Constantin Mierla Gesendet: Montag, 1.
