This issue seems to have started after snv_129 for me. I get "connect reset by peer", or transfers (of any kind) simply timeout. Smaller transfers succeed most of the time, while larger ones usually fail. Rolling back to snv_127 (my last one) does not exhibit this issue. I have not had time to narrow down any causes, but I did find one bug report that found some TCP test scenarios failed during one of the builds, but unable to find that CR at this time. -- Brent Jones br...@servuhome.net _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
