Processes that do not hang, exit on a segmentation fault or a bus error but no core ... :-((

Hi Peter, When you do a tusc, do you see the process looping on 'sendfile' ?. If 'yes', I believe it's a transport layer bug (and we need some system information), and I've been trying to duplicate it for the last couple of months, without any success. It'll be nice if I can get access to the system when the bug is showing up (I know it's a long shot). But, if that's not possible, here are a couple of things that you might want to try :
1. Update to the latest ARPA and transport patches on your system 2. Use 'EnableSendFile off' in httpd.conf
Thanks -Madhu

Hi,
a couple of weeks ago I upgraded our servers from 2.0.43 to 2.0.46. Since then, child processes on our internal server either exit with a segmentation fault or keep running but take all CPU power. Hanging processes occur at a rate of about 5 per hour. As far as I can see the URLs they are serving are not special and work fine with other child processes - however, they are all proxy requests.
We are using two apache 2.0.46 is a proxy chain, the internal webserver hands all requests to the external apache 2.0.46. The external apache does not have that problem, however, when an error occurs connecting to a remote site or when an invalid status line is received, I noticed it does not exit cleanly and an 'invalid status line' error is received also by the internal server.
I tried to SIGQUIT a hanging childprocess to get a core but it does not respond ... Is there a way to make a child process core ( I didn't find a core anywhere ) when receiving a segmentation fault ?
The systems are HPUX 11.0 .
Thanks in advance !
Peter.
