But the list in the mail CLSNL> client list view is correct. I don't belive it's a problem with nfs/zfs server. Please try with simple dtrace script to see (or even truss) what files your imapd actually opens when you click E - I don't belive it opens E and you get F contents, I would bet it opens F. -- Best regards, Robert mailto:[EMAIL PROTECTED] http://milek.blogspot.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
