Is there anything consistent about these failed checksums? Do they occur in a specific file or a set of certain files?

This is interesting -- there *is* definitely a consistency, it always happens in one of three files. One is 8k lines long (the main file from the jpgraph suite), the other two are shorter than a page in length. But it's quite hard to find any similarity between them.

How'd you gather that they're not serving any requests? Did you try to strace any of these stuck processes to see what they're doing? Did you look at what mod_status says they're doing?

I can watch them for hours in the apache mod_status view, and they'll show the same last request. They won't respond to a kill -15, I have to kill -9 them. Strace reports they're doing absolutely nothing. Russ
