I'd start with testing your RAM with memtest86 or memtest86+. ZFS errors without reported checksum errors may be the sign of bad memory. I.e. data gets corrupted before ZFS gets to calculate checksum and later invalid data with valid checksum gets written to disk. --ArtemReceived on Mon Oct 03 2011 - 20:20:00 UTC
