Hi there,

I made a simple mod_perl change to the config and when restarting Apache I got this error:
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:2250
no listening sockets available, shutting down
/usr/local/apache/bin/apachectl: line 87: 16512 Segmentation fault $HTTPD $ARGV

I then backed out the change and retried, got the same error.


killall httpd

then try it again :)



httpd was not running and I have been running Apache 2x with mod_perl 1.99x for over two months now. It started with a problem I traced to env. var $ENV{HTTP_ACCEPT}. I figured out that I needed PerlOptions +SetupENV. So I added this, stopped and tried to start Apache. That's when I got this shock.



In other words there's an Apache still running when you're trying to
start a second one which wants to listen on the same socket that the
first Apache is already listening on.  That isn't permitted.

But you shouldn't be getting segmentation faults in that case so
something else is probably wrong too. Did you build from source? Did you follow the instructions in the Guide? Linux? 1.3.27/1.27?
DSO? Maybe you can post the information requested in the docs?

There has been no change to Apache httpd.conf other than the addition of PerlOptions +SetupEnv which I commented out anyway.

How can I get a list of ports being used so I can kill the processes? As far as I can tell httpd is not running. The IP is 208.179.25.28

I dont see any apparent signs of hacking either.
