Ugh, that's not a good behavior.

Could you capture traffic and replay that with Bro instead of sniffing
the interface directly?  If you did that you could at least verify
that the problem is deterministically replicable and then we could
possibly look into the problem with you.  I have several thoughts
about what the problem could be but they're ultimately fairly long
shots and could likely be wrong.
