I am seeing this error weekly in the sql server log with associated performance hit:
WARNING: EC 5c3320c0, 9 waited 300 sec. on latch 44173b2c. Not a BUF latch.
Has anyone resolved this error?

This error usually means that your disk isn't responding fast enough. You may have a disk failure comming, or a SCSI cable going bad.

If you are on a SAN you could have a bad fibre cable, or a heat problem within the array.

Or you may simple need more spindles in your array that is having the problem.

If it's a disk failure problem you will want to run a DBCC CHECKDB on the database to ensure that the database didn't get corrupted.

Check perfmon and look for high queueing or high latency to the disk.
