I have some problems with NFS. Actually, I think, with cached data. (May be that's not NFS problem, but I wanto understand where it is) My test is very simply: two processes on two machines. First process writes data to file via NFS. Then second process reads this file and checks. Then first writes another data, and then second reads it and checks. (Totally 10 iterations). All times processes are syncronized. First ---WRITE--+-----------+--WRITE2---+-------+--... | | | ...

Can you help me in this case?
