Re: Process check always running restart script

[Brian Youngstrom]

I feel really stupid.  I had a patch in my spec file that increased the
size of bufsize to support a large number of classes (one for every rpm
on the system).  I rebuilt the rpm after upping the rev, but not
removing the patch.  Removing this patch, all is well.

Before I found this, I created two configs: one with problems, the other
without.   I found in the -d2 run of the problem configs' '/bin/ps auwx'
that it wasn't returning data.  The working configs' run of ps was
returning data.

Sorry to have bothered everyone  :)
