I recently started having a problem with tcp connections in one of my =
jails.
Im running 4.9-stable
both sendmail and perdition experience the same problem. I even tried =
stopping
everything on the box and the problem still persists.
Connections to other jails on different ip's on the same box are fine.
There seems to be about a 5 second delay.
=46rom this snippet of a ktrace I did you can see what looks to be a =
delay of about 5 seconds after the CALL kevent

Any ideas of what I can do to figure this out?
Thanks,
