We face the call issue yesterday after seeing below error in master server. All calls are failed to proceed to queue but IVR still can be processed. It had never happened before. Only when we rebooted master server manually and swapped to secondary server, the call were back to normal. Please help check how to prevent this issue.

We assumed this problem was related to chan_sip and we migrated all extensions and trunks to pjsip. Later we found warning messages that says ‘task processors exceed 500 scheduled task’ messages and found AMI stopped and PJSIP endpoint registration decreased. Finally we increased asterisk max file to 50K and MWI value to double. So far it seems fine.
