As suggested I just stopped vmware and removed the modules from memory.
lsmod did not show any VM modules anymore.

then did a sync and AGAIN!!!
#ps -lwa | grep sync
0 0 1051 994 1 0 1020 324 wait_on_dqu D ? 0:00 sync
or
#ps -lwan | grep sync
0 0 1051 994 0 0 1020 324 c0133151 D 8800 0:00 sync

I've attached both full ps.
maybe this could be of any clue to someone?

Thanks
Andre
