[DragonFlyBSD - Bug #2364] (Closed) panic: lockmgr: locking against myself

[Matthew Dillon via Redmine]

Issue #2364 has been updated by Matthew Dillon.

Status changed from In Progress to Closed

Fixed in commit 44480e310a5e2fdec131e9154d62ac8fb0f011a9.  However, there are still potential deadlock situations due to the same recursion VM fault issue that have not yet been resolved.
