This answer does NOT really relate to bayes!
But nevertheless to a typical 'out of memory'.

My 'own way' to create this Problem always was to create
selfmade rules which contained 'badly behaving regexps'.
Those are especially all things where 'multiply allowed
somethings' are again 'multiply allowed', like
/...(...[abcde]+...)*/ or /.....(\S+)*.../ or something like
/(word1.*word2|word3.*word4)/
In those cases the regexp-analyser walks through horrendous numbers
of alternatives which all have to be 'remembered' until it is known
whether to fail that pattern.
As 'spamassassin' reads the whole body as ONE string, those
'remembered' partial decisions bloated my spamassassin up to
750M for a 2M Mail (crashing the process shortly after).
So I had to fix my private ruleset to never use 'unlimited'('*')
alternatives but ALWAYS and ONLY use 'reasonable limits' like
/...\S{1,50}.../.
May be this helps?
