I tried to reproduce the problem on a second box with HEAD from some
days ago and failed up to now.
What I have found so far doing live system debugging ist that on the
machine showing this problem the initial jail (id 1) that should
be gone already still has a reference count of 2:
(kgdb) print allprison->lh_first->pr_list->le_next->pr_list->le_next->pr_list->le_next->pr_list->le_next->pr_list->le_next->pr_id
$9 = 1
(kgdb) print allprison->lh_first->pr_list->le_next->pr_list->le_next->pr_list->le_next->pr_list->le_next->pr_list->le_next->pr_ref
$10 = 2
So it seems we are leaking some creds somewhere.
What I should know from you:
a) which branch are you running? RELENG_{5,6} or HEAD
b) if it's not a RELEASE which exact build dates?
(something like uname -s -v would be a good starting point)
c) are you running with any patches like multi-IP jail patches?
d) Do you know a way to successfully reproduce it all the time?
