Is it possible that these sleep processes are being signalled by some other process? I've known a cluster scheduler to send excessive signals to running processes. You'd expect to see something on stderr in that case as far as I know, but depending on how this is being run you might not be capturing that. jh

If so you should be getting your support from RedHat. Or do you have CentOS 5.5? Its not clear from what you've said, its rather ambiguous.
