for tracing, download the trace-cmd program and use it to record and report the
events:

$ trace-cmd record -e <events>
....
^C
$ trace-cmd report > events.txt

As to the problem being memory reclaim related - that's not necessarily the
case. That's when the problem is tripped over, but it doesn't mean that this is
the cause. I'm starting to think that you might have dodgy memory or some kind
of memory corruption occurring because we haven't changed anything in the code
where the crash is occurring for several releases...

Dave.
