hi,
I have problem with mount_nullfs and jails. My system FreeBSD 5.4-STABLE
when have two jails and each of this jails has couple mount_nullfs freeze
without kernel panic. It freezes out in random times. Sometimes it can run
for couple days sometimes it freezes after couple hours.
I have mount points like below:

When i start sshd jail with mount_nulls like above i will have crash after
random period of time.
Without this jail i have never had any freeze. home dir in users jail is
mount_nulled from /crypto
partition.Earlier my users jails didnt have mount_nulls, i have had copy of
each dir. I could have
uptime like 80 days. I dont know why it is so instabile?
Could any one point me somehow ? Maybe i do someting wrong or someting?
THX
