<div dir="ltr">Hi,<div><div>We are using Kamailio with Jitsi client where we observed sometimes Kamailio stops responding to sip messages. As a result, my Jitsi client goes offline and never back online.

Also in the Kamailio syslog there are no error logs(debug enabled) related to this issue.

 As a temporary workaround, we had to restart the Kamailio server all the time.</div><div>Does anyone observed a similar issue and can suggest any resolution.</div><div><br></div><div>Kamailio version:-</div><div>version: kamailio 5.3.5 (x86_64/linux)<br>flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED<br>ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB<br>poll method support: poll, epoll_lt, epoll_et, sigio_rt, select.<br>id: unknown<br>compiled with gcc 7.5.0<br></div><div><br></div><div>UDP process when Kamailio stops responding:-.</div><div><br></div><div>root@ip-10-68-16-14:/home/ugiri# kamctl ps<br>{<br>  "jsonrpc":  "2.0",<br>  "result": [<br>    {<br>      "IDX":  0,<br>      "PID":  15436,<br>      "DSC":  "main process - attendant"<br>    }, {<br>      "IDX":  1,<br>      "PID":  15442,<br>      "DSC":  "udp receiver child=0 sock=<a href="http://10.68.16.14:5060">10.68.16.14:5060</a> (<a href="http://100.26.5.214:5060">100.26.5.214:5060</a>)"<br>    }, {<br>      "IDX":  2,<br>      "PID":  15443,<br>      "DSC":  "udp receiver child=1 sock=<a href="http://10.68.16.14:5060">10.68.16.14:5060</a> (<a href="http://100.26.5.214:5060">100.26.5.214:5060</a>)"<br>    }, {<br>      "IDX":  3,<br>      "PID":  15444,<br>      "DSC":  "udp receiver child=2 sock=<a href="http://10.68.16.14:5060">10.68.16.14:5060</a> (<a href="http://100.26.5.214:5060">100.26.5.214:5060</a>)"<br>    }, {<br>      "IDX":  4,<br>      "PID":  15445,<br>      "DSC":  "udp receiver child=3 sock=<a href="http://10.68.16.14:5060">10.68.16.14:5060</a> (<a href="http://100.26.5.214:5060">100.26.5.214:5060</a>)"<br>    }, {<br>      "IDX":  5,<br>      "PID":  15446,<br>      "DSC":  "udp receiver child=4 sock=<a href="http://10.68.16.14:5060">10.68.16.14:5060</a> (<a href="http://100.26.5.214:5060">100.26.5.214:5060</a>)"<br>    }, {<br>      "IDX":  6,<br>      "PID":  15447,<br>      "DSC":  "udp receiver child=5 sock=<a href="http://10.68.16.14:5060">10.68.16.14:5060</a> (<a href="http://100.26.5.214:5060">100.26.5.214:5060</a>)"<br>    }, {<br>      "IDX":  7,<br>      "PID":  15448,<br>      "DSC":  "udp receiver child=6 sock=<a href="http://10.68.16.14:5060">10.68.16.14:5060</a> (<a href="http://100.26.5.214:5060">100.26.5.214:5060</a>)"<br>    }, {<br>      "IDX":  8,<br>      "PID":  15449,<br>      "DSC":  "udp receiver child=7 sock=<a href="http://10.68.16.14:5060">10.68.16.14:5060</a> (<a href="http://100.26.5.214:5060">100.26.5.214:5060</a>)"<br>    }, {<br>      "IDX":  9,<br>      "PID":  15450,<br>      "DSC":  "slow timer"<br>    }, {<br>      "IDX":  10,<br>      "PID":  15451,<br>      "DSC":  "timer"<br>    }, {<br>      "IDX":  11,<br>      "PID":  15452,<br>      "DSC":  "secondary timer"<br></div><div> }, {<br>      "IDX":  12,<br>      "PID":  15453,<br>      "DSC":  "JSONRPCS FIFO"<br>    }, {<br>      "IDX":  13,<br>      "PID":  15454,<br>      "DSC":  "JSONRPCS DATAGRAM"<br>    }, {<br>      "IDX":  14,<br>      "PID":  15455,<br>      "DSC":  "ctl handler"<br>    }, {<br>      "IDX":  15,<br>      "PID":  15456,<br>      "DSC":  "Http Async Worker"<br>    }, {<br>      "IDX":  16,<br>      "PID":  15457,<br>      "DSC":  "Http Async Worker"<br>    }, {<br>      "IDX":  17,<br>      "PID":  15458,<br>      "DSC":  "TIMER NH"<br>    }, {<br>      "IDX":  18,<br>      "PID":  15459,<br>      "DSC":  "tcp main process"<br>    }<br>  ],<br>  "id": 17709<br>}<br></div><div><br></div><div>Thanks,</div><div>Uttam</div><div><br></div><div><br></div><div><br></div></div></div>
