If so, without = observing a similar regression? 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.
