See b2e0b24f76066fc52abe4330772c41996eca8bf8 (from Sat Dec 1 09:58:21 2018). The underlying problem is still there, and if you do this you're going to h= ave some very unexpected and difficult to understand behaviour in pf, but at le= ast it doesn't panic any more. I've looked at fixing this, but there's no error handling in many of the group/interface name assignment paths and the locking .. well, either I completely fail to understand it, or it's mostly wrong. --=20 You are receiving this mail because: You are the assignee for the bug.=
