Three-minute timeout during surfing?

[Ken Ambrose]

Howdy, all.  I just upgraded my boxen to RH 7.3, and suddenly my webmail
(SquirrelMail) is taking three minutes just to bring up the login page.  I
double-checked my httpd.conf file, and HostnameLookups is set to off, so I
don't -think- it's a reverse-DNS issue.  I'm stumped.  Below is a snippet
from an ethereal dump.  Any ideas?

GET /src/login.php HTTP/1.1

 ----- insert three-minute wait here -----

Note that the top portion is all "from" me, and the bottom portion is from
the server.

Thanks!
