Well, I do not know the cause is but for the lase 1/2 day, and having turned off the cache drive usage on thiose shares, I have been moving data around like a MAD MAN with no issues. So it definately seems like an issue with cache drive usage. Not sure why because like I said I moved the cache around (there are 4) regular and SSD. Cound be HW relaed and once I have some time I have an identical server just sitting there I will swap the Boot disk and see if it matters and report back. Ill give it a day or two to confirm before I mark it solved but I am still curious about the causes. Thanks for your time.
