Debian's Apache 2.2.3
02 November 2006
With the old Apache 2.0.x, I'd sometimes see proxy errors if my JBoss server took too long to respond. It was not reliably reproducible, but it looked a lot like Apache Bug #37770 around keep-alive connections through the proxy.
Apache 2.2.3 recently hit Debian, so when I got it installed, I was pleased to see that they seem to have included the patch for this fix, and I no longer see the proxy errors. My previous approach to avoiding the issue is just excessively tuning JBoss, but that didn't even eliminate all the failures.
