Well, I thought everything was working, and was checking my email around 11:00pm the other night. I could see the bodies of messages. Then I rechecked my email around 1:00am and couldn't. So, I too thought maybe it was an antivirus thing, since it happened around midnight. So, I deleted everything in the /var/cache/phpeaccelerator file, and rebooted. Everything came back up fine. So, I did a clamscan of var/cache/phpeaccelerator to try and get it to mess up.......and everything ran ok. Came back in this morning, and everything is still ok.
So, I don't know what happened to mess up the message bodies not showing up, but it didn't happen last night. Guess I'll wait and see what happens tonight.
I thought about exclusing /var/cache/phpeaccelerator in the nightly scan, but I don't know if that is what did anything or not.
It's CRAZY
