migration issue
So this morning I migrated my server to take advantage of the ram upgrade. All went well and the sites were really flying thereafter. However, a couple of hours later the server freezes completely. No sites, no ssh access. Rebooting got everything back up and running but this is a bit scary. Has anyone else seen this? Am I likely to experience this again? Is my old disk image still there? I should add that my install is Debian Lenny but presumably that should work the same post migration??
Thanks for any feedback.
