Crash stack trace

Consistently crash FreeBSD anytime transfer rates raise above 2Gbps (every =
few
days). See attached file for kernel stack trace.

FreeBSD is running nas4free and is installed as a virtual machine over ESX
6.0u1 and mounts files to be shared over iscsi from an EqualLogic SAN. Once
disks are mounted, NFS is used to share the files to the network. ESXi, N40=
32
switch, and nas4free use MTU of 9000+ and are configured to use a lossless
priority VLAN for SAN traffic.

I would be happy to answer any questions about our setup to help resolve th=
is
bug.
