             Summary: Deadlock in Hangup Scenarios with concurrent command pri show span X
                 Key: ASTERISK-28605
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-28605
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: PBX/General
    Affects Versions: 16.6.0
         Environment: Asterisk 16.6 CentOs 6
            Reporter: Dirk Wendland
            Severity: Critical


We have a Szenario with an high Call Flow ( load tests ).
Szenario:
4 S2M Ports => 60 channels go up in the same second 60 Channels hangs up in the same second
Every few seconds we check the ISN Lines with the command:
pri show span X
After a few iterations asterisk will stop working.
On the console we can fire up that command only one time then that command line interface hangs.

localhost*CLI> pri show span 4
Primary D-channel: 109
Status: Up, Active
The next ( Switchtype ) will not be printed
-----------------------------
We found the patch/task that created that issue.
https://issues.asterisk.org/jira/browse/ASTERISK-28525
If we revert that commit everything works fine.

Greetings
Dirk
