 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?
 
 
 Greetings
 Bjoern
