             Summary: Error `Too many open files` occurs after about ~8000 calls when using mixmonitor
                 Key: ASTERISK-30198
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-30198
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Applications/app_mixmonitor
    Affects Versions: 19.5.0
         Environment: Linux debian-buster 4.19.0-21-amd64
            Reporter: Julien Alie


Crash occurs because file descriptors are not freed until all resources are exhausted.  

This issue happens when mixmonitor is configured to play `beep` on stop (flag P).  When call is hungup before manually stopping mixmonitor, it attempts to play `beep.slin` but will fail and file descriptor for beep will never be released.  

Current workaround to avoid the issue is to disable the beep on stop (remove flag "P")
