I just put 0.8.8 up on www.msstate.edu, a Solaris 2.4 server. It
started fine and appears to be working fine. It hasn't been running long
but it has processed a few thousand requests and forked up to a total of
42 simultanious servers. We were running 0.8.6 before, again with no
problems across several days of continuous and busy operation.

It won't help right now, but maybe Apache should write some
kind of check list to the error log during startup/restart, e.g.

Startup: reading srm.conf
Startup: srm.conf read
Startup: creating scoreboard file /tmp/htstatus.a12345


Then the silence can be read as a meltdown during that stage.

It could make life a lot easier in the long run.

Of course these needs to be invoked with a -verbose type flag :-)

FYI --- looking at that trace, it could be that he's starting the thing
up with a relative path to ServerRoot on -d, and it's reacting REALLY
badly when it can't find the files after a chdir for some reason. I
*hope* it's a config-dependant problem...

Sigh... about the only way to make progress on this is to get, at the
very least, a backtrace showing where it is dumping core on the guy
(and preferably running it under gdb; -X is real good for this); a
syscall trace isn't really helpful.
