I wanted to say thanks Jon, I am still talking with my consultant about how to proceed - but I didn't want you to think I was ignoring your help. I actually think I am running with PERL_SIGNALS=unsafe - I say "think" because I use a special housekeeping system Kevin made to control everything and it appears like that is in there, but I want my consultant to double check for me. I'm also discussing the affects of MaxServers 0 because of an old post from Mike basically saying MaxServers 0 under anything but RPC leaves you open to DDoS... not that that is a huge concern for this site. Incidentally, I am moving slow/cautiously because since my post to the list, there has not been another occurance. However, there has been a few more of those "non descriptive" errors, but either the order eventually went through, or there was no ghost charges in Authnet - so as of right now I am treating that behavior as more clues to what is going on. Best, Paul
