Persistent Reservation with iSCSI

[oruchreis]

Hi,
I was using iscsi with 7.2, now I've updated freenas. I have two nodes which boot from iscsi in a cluster. About 2 years, I didn't face any problem with iscsi, but after the update the nodes freeze sometimes
and I have to reset them manually. It is very frustating. The nodes don't contain any data so there isn't any fatal problem. But everytime I have to reset them by hand and it annoys me much. I think sometimes the persisten reservation lost on the istgt, I don't know exactly. Anyone faced this issue? What can I do?
Regards

I think my problem is in jumbo frame/nic configuration. I have two stge(Asus NX1101), two em(Intel Pro/1000), and two igb(Intel PciE) in total in two servers. Normally, these drivers come with kernel, but I'll try to load them manually with loader.conf. I got if_stge.ko, if_em.ko and if_igb.ko from frebsd's ftp. I'll write the test result in here.

Regards.
