Asterisk is suddenly stopped responding

Asterisk Asterisk Support

Hello,

Asterisk version: 11.11
OS: RHEL 6.4 (64-Bit) with 1000 HZ kernel timing
Environment: Dedicated Server with 6 GB RAM

Problem: Asterisk is suddenly stopped responding

I configured Asterisk server and every thing works well. But, suddenly Asterisk stopped responding to our SIP devices. At that time, my OS box is connected with the internet network. But, our SIP devices are unable to connect with the Asterisk and unable to register also.

Once I restart our Asterisk, everything works fine again.

I don’t understand where and what the problem is.

Any hints or help would be appreciated.

Thank you.

Sounds like a deadlock, if you recompile and enable the DEBUG_THREADS you can use core show locks outside the cli(using asterisk -rx) and see what module has the issue.

I’d say you’re going to experience more joy when using SRV lookups or dealing with situations where your DNS server stops responding by having a look at chan_pjsip in Asterisk 12.

Matt Jordan’s comment on the first-linked issue is still true.
