[SR-Users] Segfault in 4.1.6

Hi all, I’ve had Kamailio running nicely for nearly a year, but have hit a segfault twice since upgrading to 4.1.6 earlier this week. The log shows: Oct 2 11:28:03 localhost /usr/sbin/kamailio[1222]: : <core> [pass_fd.c:293]: receive_fd(): ERROR: receive_fd: EOF on 23 Oct 2 11:28:03 localhost kernel: [11259.904645] kamailio[1206]: segfault at 58 ip 00007fa56fba0f86 sp 00007fffea594ca0 error 4 in dialog.so[7fa56fb63000+54000] Oct 2 11:28:03 localhost /usr/sbin/kamailio[1175]: ALERT: <core> [main.c:777]: handle_sigs(): child process 1206 exited by a signal 11 Oct 2 11:28:03 localhost /usr/sbin/kamailio[1175]: ALERT: <core> [main.c:780]: handle_sigs(): core was not generated Oct 2 11:28:03 localhost /usr/sbin/kamailio[1175]: INFO: <core> [main.c:792]: handle_sigs(): INFO: terminating due to SIGCHLD Oct 2 11:28:03 localhost /usr/sbin/kamailio[1220]: INFO: <core> [main.c:843]: sig_usr(): INFO: signal 15 received …. The first two lines above seem to be the important parts. Nothing was logged for about 10s prior to this extract. An earlier instance of the issue showed almost the same details: Oct 1 20:39:12 localhost /usr/sbin/kamailio[1219]: : <core> [pass_fd.c:293]: receive_fd(): ERROR: receive_fd: EOF on 23 Oct 1 20:39:12 localhost kernel: [554502.639227] kamailio[1207]: segfault at 58 ip 00007fd62c5c6f86 sp 00007fffd77c9890 error 4 in dialog.so[7fd62c589000+54000] I’m trying to catch a core next time it occurs, no core is available yet. Is this a new issue in 4.1.6? Any suggestions about the likely cause? Cheers, Dave.
