Hi, I have been picking away at this a little, and my strace looks a
little different then the other one posted, perhaps it has something to
do with the "-f" which also is supposed to trace child processes.
Anyway, this is what I used to generate the trace:
strace -f -t -p 3468 -o /tmp/strace.cron.log
What I am seeing in my trace is that EVERY time the segfault is
preceded by activity involving /etc/group (its always the same....)
I don't really know how to interpret this trace or how to take it
further / deeper, if there is anyone fluent in strace suggestions are
welcome.
