Shawn, Several people have reported issues with this, and after some investigation on my system and by trawling through the code, the whole area of database locking for Bayes and AWL is a mess. What seems to be happening is that a race condition occurs where one slave has a lock on the database, a second slave tries to lock the database and finds the existing lock, the second slave decides the lock is too old to be current, but before it can delete the lock, the first slave has either unlocked the file, or another slave has broken the lock instead.
The solution is to use a proper database - the latest SA has support for MySQL, which will be much more stable and on large databases will also probably be faster. The filter timeout in your log is more of an issue - if the filter is not completing scanning quickly enough, then either your timeout is set too low, the system is overloaded, or you are doing too much scanning. Particularly for large CAD files, are you skipping virus scanning and SPAM classification in both directions? I would tend to treat any message of more than about 200Kb as definitely not SPAM, and anything over 1Mb as highly unlikely to be a virus, so would skip these inbound. Outbound, I do no SPAM checks at all, relying on my users being sensible and our systems being secure. Best Wishes, Paul. __________________________________________________ Paul Murphy Head of Informatics Ionix Pharmaceuticals Ltd 418 Science Park, Cambridge, CB4 0PA Tel. 01223 433741 Fax. 01223 433788 _______________________________________________________________________ DISCLAIMER: This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to which they are addressed.
