I have removed one of four memory capsules - panicked again.  Will rotate

I have run memtest86+ over night - no errors found.

I have installed smartmontools - no errors found, short and long self tests
on both disks run fine.  zpool scrub repaired 0 errors and has no known data

Thank you for your advice.
