...I am trying to start up a v2.0.45 httpd server on a Redhat v7.3 box, however the startup bombs with the following error:
As can be seen, any preexisting file is supposed to be erased before an attempt is made to create a shared memory segment, so in theory "file exists" should never happen.
Well, you don't need to use named-based scoreboard on Linux. Just remove the ScoreBoardFile directive.
Even though, named-based scoreboards should work. But, you need to indicate which shared memory system your APR is using. Then, you need to see where exactly the error is coming from within APR - what system call is returning it? What does the man page say for that call?
It could be that your system is out of semaphores. You may want to see what ipcs reports and perhaps delete a bunch of stale ones (mod_rewrite eats semaphores for lunch). That's a pretty common occurrence. -- justin
P.S. The fact that your system is complaining that the pid file is overwritten may indeed mean that there is another httpd running.
