[SR-Users] Crash kamailio 4.3.1

After upgrading to kamailio 4.3.1 and modifying the config, I get this crash very often: ... CRITICAL: <core> [pass_fd.c:275]: receive_fd(): EOF on 21 ALERT: <core> [main.c:728]: handle_sigs(): child process 9341 exited by a signal 11 ALERT: <core> [main.c:731]: handle_sigs(): core was not generated INFO: <core> [main.c:743]: handle_sigs(): terminating due to SIGCHLD INFO: <core> [main.c:794]: sig_usr(): signal 15 received INFO: <core> [main.c:794]: sig_usr(): signal 15 received INFO: <core> [main.c:794]: sig_usr(): signal 15 received ... Is it known ? or may be related to my config ? Thank you Thibault
