CPU usage is minimal, it appear to be waiting for more data from the Oracle box. We are working with the administrators to determine what is going on from their side. I believe it is somehow connected to firewall issues.
I've used truss and it shows that the last thing issued was a read. The point where it freezes looks like this:
The '(sleeping...)' line is always the last thing printed. We've ruled out the IPS (Intrusion Prevention System) because we shut it completely off with no apparent change in behavior. We've also snooped the Perl box and it appears to confirm that the program is waiting on read results. Although I am worried about the cause, I'm more concerned now with finding a methodology that will terminate the program gracefully and alert us to the problem. Even if we do determine the source of the problem (I'm fairly certain we will), we'll still have the threat of similar problems in the future. In reply to Re^2: Fetching Madness
