Now that you mention it - yes, there still is a problem as far as I know.
https://bro-tracker.atlassian.net/browse/BIT-328 seems to be the

This probably means that we will either have to limit p1 & p2 to only be
allowed when Bro is not processing traffic yet too - or fix the cleanup of
the DFA data structures.
