<div dir="ltr"><div>Hi Team</div><div><br></div><div></div><div>Our opensips production server has run for almost 5 years with no issue until recently we notice little hiccups from the server graph.</div><div></div><div></div><div><br></div><div>The symptom is:</div><div>The opensips stops responding to any packets for 30 seconds, and then back up online and continue process requests.</div><div></div><div>We noticed during that 30 seconds, the CPU of opensips processors hit 100 and opensipsctl trap complaints "Can't access memory address"<br></div><div></div><div><br></div><div>The server hosts about 35k subscribers and 1500 concurrent calls during peak hours. Opensips only handles signalling, media is handled by rtpengine servers and upstream SBC gateways.<br></div><div>This happens almost every day in the production environment Mon-Fri, and less frequently during weekends. There is no big boost of subscriber numbers or calls in past couple of months.<br></div><div><br></div><div>
We are running opensips 2.4.8 on Debian 9, installed from opensips APT(which is not available now), It's an anycast deployment
</div><div>opensips -V<br>version: opensips 2.4.8 (x86_64/linux)<br>flags: STATS: On, DISABLE_NAGLE, USE_MCAST, SHM_MMAP, PKG_MALLOC, F_MALLOC, FAST_LOCK-ADAPTIVE_WAIT<br>ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535<br>poll method support: poll, epoll, sigio_rt, select.<br>main.c compiled on with gcc 6.3.0</div><div><br></div><div>opensipsctl trap output has been attached (replaced some sensitive data)<br></div><div><br></div><div>
Just wondering if anyone can shed some lights on this? </div><div><br></div><div>Let me know if extra info needs to be provided.</div><div><br></div><div>Regards,</div><div>Will J<br>
