Ok, so I tried as you suggested (except MaxClients gives me a syntax error
and I left it out.
Hopefully it's not critical - I am testing with 8 clients at this point...)
I still get a fairly reproductable crash. "Fairly reporductable" means that,
*when* I can start the debugger, the program is wedged in the same point
(with the looks of being in the process of dereferncing a bad pointer). I
could make this happen with as few as two nearly simultaneous request. A
stack trace follows. OTOH sometimes the debugger does not start, probably
meananing apache has died an even more painful death, for some reasons.
A stack trace follows.
Cheers,
