hang time, segfaults
This is way too generic, and I apologize, but maybe someone will have had a similar problem and be able to clue me into what I should be looking at. The server's running on the testbed (Apache/1.3.12 (Unix) mod_perl/1.23 mod_ssl/2.6.4 OpenSSL/0.9.5a, with an automatic redirect from 8080 to 8443), but not quite perfectly. :o/ It hangs a lot, especially on page reloads. Sometimes it delivers pages perfectly, other times it takes half a minute. The other day the error log piled up with several dozen segfault child expirations while checking it from a coworkers desk, which probably explains the empty document pages he kept getting. I have no real clue why. The one thing amiss I can find is probably just ignorance on my part. When I telnet to the server, it's return output includes numbers that I am not seeing in my web pages, which are no logical part of the output that I understand, and aren't there from the normal server. Specifically (as an example), I'm getting 15a as the first line of actual text after the blank line that ends headers, and a 0 two lines after the /BODY/HTML line that ends the page the server sends at the end of the 302 message from the page I requested (which 302 is correct server behavior, btw).

The other day theerror log piled up with several dozen segfault child expirations whilechecking it from a coworkers desk, which probably explains the emptydocument pages he kept getting. I have no real clue why. Check your SSLRandomSeed and SSLSessionCache settings. Your SSLRandomSeed might be set to a blocking source of entropy (such as /dev/random as opposed to /dev/urandom on some platforms). You might be using a DBM Session Cache and be using a broken DBM library. What are these set to for you?
