Re: Strange behavior - load high when scanning mail from one specific user
[In reply to]

Thank you for your suggestion!
I listed the content of the user's .spamassassin folder and found some files
that were not on the other user's folders, such as:
bayes_toks.new
bayes.lock
I renamed all the files and have been monitoring the server for over an hour
and the problem has not occurred again. The files have been recreated and
the user has received new emails since the change without a problem.
Thank you again!
