Experienced multiple crashes in a row, and it wouldn't stop until I downgraded to 2.2.1.

Looks like it's trapper # 11, around processing some lld info.

If someone can help me debug what hosts/templates are involved, I'll provide more info about what those contain.
(I have a few custom LLD rules in place, but I can't read this:
