Dear Monks,

I have discovered that there can be a problem restarting Apache 2.2.6 on Windows when mod_perl is installed. If you run "httpd -k restart", Apache can fail to start and produce the following type of errors in the Apache error.log: 

[Wed Jan 02 10:26:41 2008] [crit] (OS 10106)The requested service prov
+ider could not be loaded or initialized.  : alloc_listener: failed to
+ get a socket for (null)
Syntax error on line 53 of C:/Apache2/conf/httpd.conf:
Listen setup failed
[Wed Jan 02 14:06:25 2008] [crit] (OS 6)The handle is invalid.  : mast
+er_main: create child process failed. Exiting.

In my case, line 53 (cited in the error above) was simply: "Listen 80", which was working fine prior to the attempted restart.

After consulting on www.apachelounge.com, I learned that this a recently reported mod_perl bug.

One workaround is to use "httpd –k stop" followed by "httpd –k start" rather than "httpd -k restart". This approach resolved the problem for me.

Hope this helps.

Update: I decided to post this because it was not at all obvious from the error (at least to me) that the problem was a bug in "httpd -k restart". It looked more like a configuration issue, which had me on a wild-web goose chase for a while.
