It looks like RT is a bit of a memory pig (in the nicest possible way!) How much memory do you have in your machine?<br><br>Cheers,<br>David<br><br>----- Original Message -----<br>From: "Sebastien Termeau" <st@mobilepeople.com><br>To: rt-users@lists.bestpractical.com<br>Sent: Wednesday, 20 August, 2008 11:22:13 PM GMT +10:00 Brisbane<br>Subject: [rt-users] Problem after an upgrade to 3.8.1<br><br>Dear RT-Users,<br><br>I have a really recent RT 3.6.7 installation (around 200 tickets)<br>running on CentOS 5.2.<br>I was able to upgrade to 3.8.0 without problems.<br>The problems appear when I tried to upgrade either from 3.6.7 to 3.8.1<br>or from 3.8.0 to 3.8.1.
