Unfortunately I cannot directly help you here. My only iSCSI target server is
still on 10.4 ...

But a suggestion:

Install the latest BETA of FreeNAS (11.2-BETA2), and try if that shows the same
problems. It's based on 11.2-STABLE. If not, the FreeNAS source tree and/or the
community might prove helpful. Heck, possibly their ctld config contains some
tuning your's doesn't. Communication is via forum instead of mailing lists,
but they are a generally kind bunch of guys.

I figure the number of actual users of iSCSI might be larger in that community.

HTH,
Patrick
