[asterisk-bugs] [JIRA] (ASTERISK-28093) Asterisk Deadlocks with High Load

[Nicolas Tanski (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-28093?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Nicolas Tanski updated ASTERISK-28093:
--------------------------------------

    Description: 
Hi Team,

we are experiencing frequent crash issues in the Asterisk instance, we are using our own dialer solution with AMI protocol.

The Asterisk service operates on average with 250 simultaneous calls, 40 record calls, the load is between 1 and 3, in some cases the load quickly rises to 10, which causes the rejection of new calls and the instance of Asterisk does not respond.

We were only able to restart the service by killing the Asterisk service with the Kill PID command.

It was enabled the flags DONT_OPTIMIZE, BETTER_BACKTRACES and MALLOC_DEBUG to try identify the problem.

Summary
Average simultaneous calls: 347
Average record calls: 40
Load Average: > 1 and < 3
High Load Average: 25.26

After the crash in Asterisk, we execute the commands and the service returns to normal operation
\# kill -9 PID_ASTERISK
\# /etc/init.d/asterisk start
