Getting error handling right in procmail requires jumping through hoops
and adding an error trapping recipe after each and every action that you
code, that's why I'm advocating replacing procmail.

While you're writing in a later message that you've found the cause for
the allocation errors, I still believe that the error non-handling in
your procmailrc setup persists. Reason why I think that: Fetchmail
6.3.26 in default configuration will leave mail on the server and retry
it later (--softbounce is default), but for that to happen it needs to
know that the --mda failed, either by it crashing, or from its nonzero
exit status. Since you wrote about mail loss, I believe that procmail
hasn't propagated that script failing status back to fetchmail.
