Looping MessageException causes system stall

• Key: JAMES-153
• Type: Bug
• Status: Closed
• Resolution: Fixed
• Priority: Critical
• Assignee: Unassigned
• Reporter: Oliver Draese
• Component/s: MailStore & MailRepository
• Affects Version/s: 2.1
• Fix Version/s: 2.2.0

Description

James hangs and creates looping exception stack traces within the log files until the filesystem runs full and the complete Linux box hangs. The following exception stack trace is added again and again (several 1000 times) to the phoenix.console log file in the phoenix temp directory, what causes an increadible big log file in temp, so that no filesystem space remains free:

In the james log, the following line is repeating several 1000 times:

In the maillet log, the following exception is repeating several 1000 times:

In the mailstore log, the following error sequence is repeating several 1000 times:
17/02/04 06:44:41 ERROR mailstore: Exception storing mail: javax.mail.MessagingException: Unknown encoding: text
17/02/04 06:44:41 ERROR mailstore: Exception storing mail: javax.mail.MessagingException: Unknown encoding: text

17/02/04 06:44:41 ERROR mailstore: Exception retrieving mail: java.lang.RuntimeException: Exception caught while retrieving an object, cause: java.io.FileNotFound
Exception: /opt/james-2.1.3/apps/james/var/mail/spool/4D61696C313037363939363638313837372D353239373934.Repository.FileObjectStore (No such file or directory), so
we're deleting it... good riddance!

The other log files seem to be OK. Wouldn't it be enough to show trace the exception once, instead of looping it to all logs? This error occurrs on my system at least once per week what causes me to have an extremely instable mail server environment because the filesystem is running full all the times and I have to delete all the logs before I can go on.

Please let me know, if you need any further information to solve this problem
