[Freeswitch-dev] Strange bug...

There seems to be a leak somewhere. We're chasing down a leak that we
detected the past weekend after we finally got the whole weekend running
freeswitch under severe stress and glare scenarios. The OOM killer kicked in
at some point.
We've found that even non-glare scenarios are leaking. Since we just
introduced a new stack, we're unsure at this point whether is our new stack
or something in FreeSWITCH. However, after running valgrind, using
MALLOC_CHECK_ and mtrace(), those tools report issues at switch_event.c,
where one of the headers value being freed was never allocated (and
therefore may be the value that was really allocated is not being freed), or
is some kind of heap corruption. Many hypothesis at this point, nothing
Just thought in letting you know, it may not even be the same issue.
