It may have been fixed in the patches sin= ce then. I did get another symptom that might have been related before, which = is the jails failing to unmount on jail -r with "Device busy". Previously we traced that error to TCP connections being left open in TIME_WAIT state, bu= t on the server that used to crash it happened always even if the jail had just = been started. Since then we had solved it with a tcpdrop script as an exec.posts= top hook, but with the server I just spun up to test it it still happened a few times. Once I looked into it and couldn't find anything wrong with the tcpd= rop script I couldn't get the Device busy error to happen anymore. I'm not sure= if this is related. --=20 You are receiving this mail because: You are the assignee for the bug. You are on the CC list for the bug.=
