Dear All,

this is on a ZCS5.0.13(OSS) system, we found there's some error message in mailbox.log file :

2010-03-08 09:07:06,782 ERROR [LmtpServer-562870] [;mid=35278;] Sieve - Evaluation failed. Reason: null

2010-03-08 09:07:06,782 INFO  [LmtpServer-562870] [;mid=35278;] lmtp - try again for message exception occurred
the /opt/zimbra is located in the SAN storage and OS root file system and /opt/zimbra don't have disk space problem at that time.

does anyone see this before and any idea what's it for?
