[Mimedefang] multiplexor error

[An.H.Nguyen]

It seems to work fine after I commented out the line "lock_metho flock"

When using SA bayes with Mimedefang, is it still neccessary to run sa-learn 
regularly and manually copy spams to a folder and have sa-learn to learn 
from the manual picks?
I still don't see the bayes mark in the list of tests:
******* (7.166) 
HTML_FONT_SIZE_HUGE,HTML_IMAGE_ONLY_20,HTML_MESSAGE,HTML_MIME_NO_HTML_TAG,MIME_HTML_ONLY

Thanks,
An

This is a known issue with SpamAssassin's AWL feature - basically, flock() 
is designed for non-NFS-safe locking in a single-threaded environment, but 
MD is multi-threaded, and there are race issues between checking whether a 
lock file exists, and trying to create one.  As your system load increases, 
the likelihood of it happening grows.

Search the archives for this - it has come up several times.

Try it with the "lock_method flock" line commented out, and see whether this 
resolves the problem.

Best Wishes,

Paul.
