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?
