             Summary: memory leak manager.c:purge_old_stuff not scheduled when manager.conf enabled=no
                 Key: ASTERISK-29184
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-29184
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Core/ManagerInterface
    Affects Versions: 16.15.0, 18.0.1, 17.8.1, GIT
         Environment: Any
            Reporter: Diederik de Groot


With enabled=off in manager.conf the `purge_old_stuff` function from main/manager.c is never scheduled and doesn't run. Meaning that any time the append_event is called (for example through __manager_event_sessions_va / manager_event) new memory is allocated for the event, it is inserted in the `eventqent`, but never released. Causing a non negligible memory consumption over time. Enabling manager/ami and reloading resolves the memory leak.

Possible/Potential Solutions: 
- append_event could bail out early and not allocate memory.
- purge_old_stuff could be scheduled even if ami/manager is not enabled.
- purge_old_stuff could be scheduled on some other monitoring thread.
