Stefano Bagnara commented on JAMES-387:
---------------------------------------
I increased the total memory for my "personal" james to 800MB and it only
handle my own mail (around 1000 messages per day) but it still stop checking my
messages.
Here is the exception
20/11/05 00:14:57 INFO James.Mailet: BayesianAnalysis: Exception:
java.lang.Integer
java.lang.ClassCastException: java.lang.Integer

If I restart James it works for almost a day and then it break again.
My bayesiananalysis_spam count 853685 rows, while the ham counts 21253.
I configured james to automatically feed spam and ham for messages I recognize
so the bayesian can be improved. Maybe my continuous feeding is not good for
the bayesian mailet.
Any Idea?
Who is using this Matchers/Mailets? What are your spam/ham sizes? How often do
you feed ham/spam? how much memory you reserved to James? how much messages
through the bayesian mailets?
