 Replying to [comment:9 nicktc]:
 > No, it's not the contact module. As I said I have isolated this
 pregmatch in a single PHP file. No Wordpress, not Contact plugin. So it's
 definately something with my server, if you guys don't have this problem.
 I can tell you that on my server that pregmatch is causing a timeout.

 Nick, wanted to let you know I have the same issue on a server with the
 exact same PHP (5.2.17) and PCRE (8.02) versions -- regex timing out after
 30 seconds.
