[Freeswitch-users] Reliability of HEARTBEAT events every 20 seconds? (in mod_event_socket)

Thu Dec 9 21:25:10 MSK 2010

That didn't make a difference either.. I will have to look into this deeper, and add some more debug logging for when the event fires within FS.

No more suggestions anyone? :)

No, and all timing seems ok (both good audio and timer_test returns with good results). And we're actually talking about 10 seconds here :)

This is on Windows, and I'm starting with -hp, I wonder if I might have some kind of thread priority issue - I can't remember seeing this before adding -hp.. hmm, I will check that out.

Are you running FS with -nocal?

Ok - I trapped the problem with full event info. The up-time also reports a difference, in this case 32 seconds. As you can see there is no load on the server at all by this time, no calls etc. Hmm, this is really strange I must say.

Also do you have any warning messages like this in the fs log?
Task was executed late by %d seconds

(That should show up if the delay is in the scheduler, if the task
runs >1s  late).
