One of my arrays had a drive in slot 4 fault -- lots of reset something or 
other 
errors.  I cleared the errors and the pool and it did it again, even though the 
drive was showing ok in smartmontools and passed its internal self test.

I replaced the drive with my cold spare and a week later the replacement drive 
in slot 4 had the same errors.

Clearly it was the chassis and not the drive.  I blew out the connector on slot 
4 and it did again a week later.

Again I cleared error, cycled the power on the array and haven't had the 
problem 
in the past 5 weeks.

Sometimes things just happen, I guess.
