I have a CentOS 5.5 i686.
Apache 2.2.3, perl 5.8.8, mod_perl 2.0.4-6, OTRS 3.0.9
I have a problem which appears sometimes. I can't close a ticket.
I open a ticket, click a "Close" button and get a new window for closing a ticket.
But when I have filled a form and click button "Send", the window doesn't close. It stays open and empty.
If I close this window and refresh a page of ticket, I see that I have added a new note "Close", but a ticket has status "OPEN".

In a several time of this procefure, a ticket will be closed. And if I restart a apache (httpd) service, a ticket will be closed at once when I click "Send" in Closing window.
So, how I can solve this issue?
