I think that's about all relevant info ...
Had file on disk (not array), attempted to mv file to array. Went fine till 2.4GB was copied, then it slowed down to a meg every few minutes. Free memory was ~50MB (Typically is 1.5-2GB), and cache was 2.5GB.
I'm guessing this was your problem (workarounds suggested in the bug):

'mount -o noreservation' the FS and try it again.
