Description

While doing some heavy file transfers via nfs or cifs the network hangs and the machine eventually becomes totally nonresponsive.
A hard reboot is needed because after a "fast-reboot" the network is still not working. and the two e1000 interfaces are missing.
The nics are two on-board igb and a dual-port e1000, all configured in a link aggregation with two vlans on top.

I've had this problem with nexentastor (both commercial and community edition) and with openindiana b147 and I can reproduce it.
Sometimes it goes on for hours before hanging and often hangs after a few minutes.

Let me know if i can provide more information.
