I would venture that the HTML filter may be the problem.
The HTML filter is probably not the most efficient, especially since
it attempts to strip all kinds of markup that can be sources of
In the past, the comment declaration filtering had to be modified
since the initial Perl regex would gobble up all kinds of memory
on an reasonably-sized HTML entity.

You may want to write your own simplified HTML filter if security
issues with HTML is not a concern (i.e. you trust the source), and
see if this helps in your memory problems.
As a test, you could assign m2h_text_plain::filter to text/html
data just to see if memory could be a culprit. Or, even better,
assign m2h_external::filter for text/html since it just saves
the data to a separate file. If you do not get any memory problems
with either test, then m2h_text_html::filter is highly likely
the source of the problem.
