Good day all. We recently upgraded our SM installation from 14.5 to version 15.4.6151 and today I was looking through our logs for one of my users to find out what happened to an email that they needed delivered. The email ended up in their junk E-Mail folder but I saw something strange in their log entry for today, there were a bunch of entries right in a row that said this: folder 'Inbox' failed.  Mailbox is locked. Could this be clamav taking a long time to scan their message? Or maybe this could be because of SpamAssassin VM taking awhile to scan?

 

Anyone else seeing this type of behavior in their log file?
