When enabling AV/AS, on a certain server (5.0, upgraded to last version today) I have a runnig problem wih AMAVISD: amavisd runs on 100% processor, and seems to hang continuously. All mail is getting deferred as it cannot be passed from postfix to amavis. Disabling AV/AS is a workaround, but as this issue remains in 5.0, I'd like to find a solution.
I have been searching different fora, bugzilla's, wiki's, but I'm afraid I can't seem to find any solution on why this is happening. I already enabled some verbose loggings (smtp -v from postfix to amavis, log_level 5 in amavis), but this does not give any extra info on why Amavis itself is running loose.
Any pointers on how to start troubleshoting this?
