3 Weeks ago, the the server locked up and was rebooted. There was no apparent problem but now users are seeing that attachments that appeared normal before now are empty. When I examine them they have their contents filled with <<NULL>>.
There are also many emails with no body. All headers appear normal. The Attachments even show correct attachment size. What can cause this and what can be done to repair it?
