Bug ID: 210315
Summary: panic: destroying non-empty racct: 2113536 allocated
for resource 4
Product: Base System
Version: 11.0-CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: freebsd-bugs@FreeBSD.org
Reporter: a...@freebsd.org
I have got this panic twice so far. Both times were just at the end of a
poudriere bulk build. The problem is not readily reproducible, so it could be
that a certain port somehow provokes it.
I can provide more details. I can test any diagnostic patches.
Some details:
