Everything was working fine with Bugzilla until this morning. Now, I can
query bugs and edit bugs with no problem, but when I try to create a new
bug, after I click on the commit button, post_bug.cgi takes a long time and
finally I get a timeout message (in Firefox, "The connection was reset").
No attachments, nothing unusual about the bug contents.

I tried restarting mysql, I tried a couple of different browsers, but
nothing works.

Any ideas on what I can do to fix this?
