I'm more inclined to think some intermediary is having persistent TCP
connection problems. Caching the content will at worst result in old dead
content being served back to the clients. But still served back.
Restarting the server indicates some active connection is hung.
Could you suggest a way to diagnose persistent TCP connection problems
or suggest a forum where I might be able to table the question?
Not really. I only know how to diagnose from the bx which is having the
issue. Which means the ISP proxy in your case.
As far as the end points go you may have to dig really deep, like
tcpdump deep, to see exactly whats going where and what is coming back.
From the client end initially.
Contacting the ISP admin and enlisting their help might be of some
advantage.
I wouldn't mind marching around to the ISP offices and throwing a
tantrum, but I'd prefer to be reasonably sure of my facts before I did
so.
It's just an idea I have, so yelling may be counter productive. But
being in the middle they would certainly have the best position to look
into the problem.
