10Gig Chelsio T320e iSCSI lock up with high CPU usage

[VioletDragon]

Hi,

I have a problem all of my VMs are running over 10Gig link only to my XCP-ng and my workstation the issue is that the link on the FreeNAS completely locks up no pings and no response via iSCSI or NFS. When copying files from my Workstation it also causes the link to lock up with High CPU usage, this issue doesnt happen straight away after 5 to 6 days this happens. LAGG interface is perfectly fine but the Chelsio T3 is where the problem allies.

Any ideas?

Thanks.

Have you checked TSO4/TSO6 is enabled? Made a world of difference on my T520-CR
