[SR-Users] Kamailio crash [receive_fd: EOF on 19]

Hi, I'm randomly getting crash in my Kamailio with an error in log files like this: <core> [pass_fd.c:293]: receive_fd(): ERROR: receive_fd: EOF on 19 ALERT: <core> [main.c:775]: handle_sigs(): child process 6853 exited by a signal 11 ALERT: <core> [main.c:778]: handle_sigs(): core was generated INFO: <core> [main.c:790]: handle_sigs(): INFO: terminating due to SIGCHLD *Version of Kamailio is:* [root@kamailio /]#kamailio -V version: kamailio 4.1.4 (x86_64/linux) 39adca flags: STATS: Off, USE_TCP, USE_TLS, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, DBG_QM_MALLOC, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 4MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: 39adca compiled on 03:48:50 Aug 1 2014 with gcc 4.4.7 And gdb bt output is attached in text file. One thing out that is common in all the previous core files is this: #12 0x00000000004a54ab in receive_msg ( buf=0x924600 "INVITE sip:+17036833500@14.131.165.9:5073 SIP/2.0\r\nVia: SIP/2.0/UDP 14.55.2.43:5060;branch=z9hG4bK0eB8f68591a19b9b8f0\r\nFrom: \"Anonymous\" <sip:Anonymous@Anonymous.invalid>;tag=gK0e13e132\r\nTo: <sip:+170"..., len=1018, rcv_info=0x7fff3dbee970) at receive.c:212 #13 0x000000000053c9a8 in udp_rcv_loop () at udp_server.c:536 Does this mean that Kamailio can't understand the From Domain: Anonymous.invalid and hence crashes ?
