Re: exit status issue

[Dallas Clement]

Bob, Yes I agree with everything you've said.  I am grasping at
straws, which I really don't like.  It's very unlikely that the
problems are with any of these things I've mentioned bash, Linux
kernel, compiler, libc etc.   This script is fairly large and it does
lots of checking of block devices, raid arrays, and volumes.  All of
it is executed synchronously which should make it simple to debug.
The script itself is executed in the background as a daemon process.
This script is executed on locally mounted RAID devices.  No network
involved in the test.

I'll continue my search for root cause with a more disciplined
approach.   Thanks for the help.
