would attribute this to the problems with perl 5.6.0 and mod_perl.
...assuming of course that you haven't already updated to perl 5.6.1. Mine
does this frequently too - sometimes you do something in RT and there's no
response because that apache child process died (segfaulted), and you hit the
back button and do it again and it works. I'm not sure whether this will
impact RT in terms of data integrity, but it didn't seem to be causing problems
so I just set a netsaint check to alert when the number of apache processes
dropped below 1.</SPAN></FONT></DIV>

will be later today.</SPAN></FONT></DIV>

look fine. The http error logs are empty. There is nothing of note
