Ok, in another trace I see:
"Event socket closed, shutting down myth"
...which indicates that cmyth_event_get returned with a value of
CMYTH_EVENT_CLOSE or 1. This only happens if cmyth_rcv_length returns
zero or less. The description of that function indicates it should
return the length of a MythTV protocol message and that a success is a
positive non zero value. Going back to the dump - I see where it says
that cmyth_rcv_length failed w/a -4. And before that in the dump was a
call to cmyth_conn_destroy. Comments for this function say it is for
tear down and release storage associated with a connection. And before
that, there were many calls to cmyth_release. Many of these calls print
out "free it" indicating that this was the "last reference" and that we
need to "destroy the structure". However, eventually, it appears calls
are made to cmyth_release w/"nil" as the argument? Am I reading the
dump right? I think the transition from allocating memory to destroying
memory is the key. Here, I think I captured the beginning of when MVPMC
starts destroying memory:
