Now I get crashes related to TLS: May 5 14:58:40 dev-cpereg01 kamailio[36147]: CRITICAL: <core> [core/mem/q_malloc.c:519]: qm_free(): BUG: freeing already freed pointer (0x7f4fedbed4e8), called from tls: tls_init.c: ser_free(323), first free tls: tls_init.c: ser_f ree(323) - ignoring May 5 14:58:40 dev-cpereg01 kamailio[36147]: CRITICAL: <core> [core/mem/q_malloc.c:519]: qm_free(): BUG: freeing already freed pointer (0x7f4fedd72b88), called from tls: tls_init.c: ser_free(323), first free tls: tls_init.c: ser_f ree(323) - ignoring May 5 14:58:40 dev-cpereg01 kamailio[36177]: CRITICAL: <core> [core/mem/q_malloc.c:519]: qm_free(): BUG: freeing already freed pointer (0x7f4fedd9e4a0), called from tls: tls_init.c: ser_free(323), first free tls: tls_init.c: ser_f ree(323) - ignoring May 5 14:58:40 dev-cpereg01 kamailio[36157]: CRITICAL: <core> [core/mem/q_malloc.c:519]: qm_free(): BUG: freeing already freed pointer (0x7f4fedd9e428), called from tls: tls_init.c: ser_free(323), first free tls: tls_init.c: ser_f ree(323) - ignoring And a bit later on: May 5 14:58:46 dev-cpereg01 kamailio[36179]: CRITICAL: <core> [core/pass_fd.c:277]: receive_fd(): EOF on 34 May 5 14:58:46 dev-cpereg01 kamailio[36143]: ALERT: <core> [main.c:774]: handle_sigs(): child process 36161 exited by a signal 11 May 5 14:58:46 dev-cpereg01 kamailio[36143]: ALERT: <core> [main.c:777]: handle_sigs(): core was generated May 5 14:58:46 dev-cpereg01 kamailio[36143]: INFO: <core> [main.c:799]: handle_sigs(): terminating due to SIGCHLD Has there been a fundamental change in TLS?
