Thanks for your response Jesse. The answer that I received from the guy who manages the VM is as follows:
"Snapshots are created for the backup process but they are removed immediately after it is finished" I've confirmed that the issue is reproducible by simply letting RT sit for a couple of hours, untouched (no connections to the front end). We tried lowering the memory to 768MB and the issue is still present; so we bumped it back to 2GB. Any other ideas? Should we be entertaining the idea of moving this off of a VM? -CK -----Original Message----- From: Jesse Vincent [mailto:je...@bestpractical.com] Sent: Tuesday, April 07, 2009 4:22 PM To: Charles Kugelman Cc: rt-users@lists.bestpractical.com Subject: Re: [rt-users] Hanging Login Page (ModPerl2, HTTPD, Oracle, RHEL5) On Tue, Apr 07, 2009 at 03:58:35PM -0400, Charles Kugelman wrote: > Joop, > > Thanks for the response.
