Hi Johan,
we experience the same on 13.1-PRERELEASE. Currently trying to collect =
some evidence
(dtrace) to send to Kristof Provost who was so kind to assist. We are =
hit by the problem
in production in 12-24 hour intervals. Have not done any artificial load =
tests, yet.
May I ask you to run this dtrace script while at least one jail is =
disconnected and while
traffic is present that is trying to reach the jail? If you can afford =
to do that in production (?)
that would be great. Forward to Kristof (kp@), please.
Thanks and kind regards
Patrick
