Description of problem:
Upon a system crash (due to power and UPS failure), Apache has been "quirky".
Upon shutting down the httpd process (via # /etc/init.d/httpd stop) - SIGTERM
was sent to the child processes since they would not exit cleanly.
Now, when I attempt to start the web server I receive the following entry in
[crit] (17)File exists: unable to create scoreboard (name-based shared memory
Upon this happening - the web server main process dies. I am about to restart
the server to see if that clears up the problem.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. see description
Actual Results: see description
Expected Results: Apache should have started with no error messages in the log.
It would also be nice if the error message attempted to explain what was going
on ("file exists" does not specify which file exists) and how to work around the
$ rpm -q httpd
There are some known problems about httpd startup after power failure (e.g. bug
78019) though you shouldn't see that particular error message in the default
configuration; are you using the "ScoreboardFile" directive in httpd.conf?
Yes - though this file is largely default (I haven't touched the scoreboardfile
You can just comment out the ScoreboardFile directive normally.
I get this if I stop httpd normally;
2. Check apache is running
3. service httpd stop
4. Check apache has stopped
5. service httpd start
apache "starts" but dies
6. service httpd status
Same message as reported in the error log.
It't won't start again unless I change the scoreboard filename.
Note: I never set the scoreboard file, if it wasn't set in the supplied config
file then it must have been set by redhat-httpd-config which I tried
Can also relicate every time on my machine -
sudo service httpd restart
- always - leads to a bunch of SIGTERMS being sent to the running processes
and then I get that damn scoreboard error.
I, of course, meant "replicate" and "darn".
I am running RHL 8.0 with httpd-2.0.40-11.5 on an i686.
You should remove the ScoreboardFile directive from your httpd.conf.
This is not really a bug: if you configure a ScoreBoardFile directive then the
server will not start up after an unclean shutdown. The solution is to not
configure a ScoreBoardFile directive.
