netstat -an: bus error

[zamana]

Hi!

I have some jails running from some time, created under 11.3-RELEASE, since from FreeNAS (so before the FreeNAS->TrueNAS rebranding...)

After updating TrueNAS CORE to the latest release (TrueNAS-12.0-U5.1 ), I realized that even after upgrading these jails, they still show the same release, but the real problem is that in all of them the "netstat -an" command shows "Bus error", like this:

Code:

root@postfix:~ # netstat -an
Some tcp sockets may have been deleted.
Some udp sockets may have been created or deleted.
Active UNIX domain sockets
Address          Type   Recv-Q Send-Q            Inode             Conn             Refs          Nextref Addr
Bus error

And this:

Code:

root@unbound:~ # netstat -an
Some tcp sockets may have been deleted.
Some udp sockets may have been deleted.
Some ip sockets may have been created or deleted.
Some icmp sockets may have been created or deleted.
Some igmp sockets may have been created or deleted.
Some pim sockets may have been created or deleted.
Some ip6 sockets may have been created or deleted.
Some icmp6 sockets may have been created or deleted.
Active UNIX domain sockets
Address          Type   Recv-Q Send-Q            Inode             Conn             Refs          Nextref Addr
Bus error

I then deleted and recreated some jails with the current release (12.2), and then the error disappeared.

So, I have some questions:

1) What could cause this "bus error"?

2) Is it possible to really upgrade jails, or is it necessary to recreate them in this case?

Thanks.
Regards.
