             Summary: ARI: Crashing on json_mem_free (after sending event)
                 Key: ASTERISK-27862
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-27862
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Applications/app_stasis
    Affects Versions: 13.21.0
            Reporter: Stefan Repke


ARI is activated and there are several apps connected with "subscribeAll=true".
Then, Asterisk crashes occasionally when delivering ARI events!

With normal workload, this happens once or twice a day. It can be provoked by adding many (eg. 10) ARI subscribers and producing lots of events (eg. PeerStatusChange by registering/unregistering a peer).

I coredumped three crashes, all having a memory corruption in {{json_mem_free}} at {{json.c:84}}; cf. attached backtraces.
* Backtrace 2 and 3 have similar problems: {{double free or corruption (fasttop)}},
* Backtrace 1 looks like wrong memory access.

I've also attached the last logger messages from the CLI (debug=5 / verbose=5).
