[OT] mod_rewrite hang
If anybody could give me some insight on the problem I am having,
it would be greatly appreciated. I have been working on this all day,
and I just can't get past this roadblock.
Situation: Using mod_rewrite's RewriteMap functionality with an
external rewrite rewrite map ( a perl script ).
Tested on 3 Linux 2.2/Apache 1.3.12 webservers. Two act exactly as they
should, and one waits *exactly* 3 minutes, then does what it should.
Details:
Apache Config:
RewriteLock /var/lock/findurl.lock
RewriteEngine on
RewriteLog /www/logs/rewrite
RewriteMap find prg:/www/bin/findurl.pl
RewriteLogLevel 3
RewriteRule ^(/~.*) ${find:$1:%{SERVER_PORT}}
findurl.pl finds content on other webservers and rewrites the url.
This works perfectly on 2 of my webservers, and on one it just hangs for 3 minutes.
mod_rewrite takes 3 minutes:
192.x.x.x - - [02/Sep/2000:22:05:27 -0400] [www.tlink.net/sid#82d6724][rid#83dc41c/initial] (2) init rewrite engine with requested uri /~asdf/

The hanging occurs before it even gets to my perl script, which has me stumped.
All servers are Apache 1.3.12, Linux 2.2, perl 5.005_03.
Can anybody help?

strace the server under 'httpd -X'

Thanks for the people who tried to help, but it doesn't seem to
be a DNS timeout. When using the following code, it still hangs:
#!/usr/bin/perl -w
use strict;
$|++;
while(<>){
print "$_\n";
}
Any other suggestions?
