[rt-users] apache2 freezes on certain requests

[Alexander Reintzsch]

Hi all,

I have RT running on a Centos 5.8, apache2, perl 5.8.8, mod_perl 2.0.4,
mysql 5.0.95 virtual machine. I use ldap to authentify users.
It's been working for some time (~15 month), but after a patching of
perl last month the system seems to be a little bit messed up.

Debugging is turned on to the fullest, in apache2, mysql, perl and rt
itself. But this couldn't help me in anyway so far, since there is no
output. :-( Maybe you can give me a push to the right direction.

All dependencies are met, when I check sbin/rt-test-dependencies
--verbose --with-mysql --with-modperl2 --with-dev. (see below)

In ticketview the apache doesn't give a reply and uses 100% of the
processor (I run 'top'  to check that).
But this only happens on

Ticket/ModifyPeople.html?id=4518 and
Ticket/Display.html?Action=Take;id=4518 and

on clicking "Save Changes" when I change the owner of the ticket in
Ticket/ModifyAll.html?id=4518

Also the server only sends part of the mask and then freezes when I call
Ticket/Update.html?Action=Comment;id=4518

Here the last lines of code are:
"<textarea autocomplete="off" class="messagebox" cols="72" rows="15"
name="UpdateContent" id="UpdateContent"></textarea></td></tr><tr><td
class="label">Attach:</td><td><input name="Attach" type="file" /><input
type="submit" class="button" name="AddMoreAttach" value="Add More Files"
/><input type="hidden" class="hidden" name="UpdateAttach" value="1"
/></td></tr></table><hr class="clear" /></div></div>"

but not when I call
Ticket/Update.html?Action=Respond;id=4518
There everything works fine, it seems.

So, I'm really puzzled and have no clue about how to manage this problem
and make the RT running again.

So, I guess it might have something to do with rights, but I just cannot
figure out what. Because this happens when I'm logged in as root as
well. And I thought that root has global rights.

I also had some problems with my scrips on creating tickets after
changing from version 4.0.6 to 4.0.7 that I couldn't solve, so I turned
them of. Then at least the ticket creation worked again.

Any help is highly appreciated.
