NFS Problem 1 (Crashing)

The LTSP would create stale locks and eventually the LTSP server crashes. Furthermore, data is corrupted during the process.

Is there any type of errors in /var/log/messages? When you say crashes what do you mean? The machine oops (in that case send the oops trace) or some part of LTSP drops core....

NFS Problem 2 (Corruption)

This happens mostly in OpenOffice, more than once, data gets corrupted and when working with both Microsoft and native OpenOffice formats. On full local workstations where the files are save to the local disk, this does not happen. The office docuements are normally saved to an NFS filesystem.

Boy this is a bit bizarre..... What mount options are you using?


NFS Problem 3 (Performance)

NFS is very slow over T1 and cable links but is just fine on the Local Fast Ethernet. It is slow enough to either knock people off or cause write errors. We are thinking the hubs play a major role and are replacing with high end managed switches. However we believe that there is more than meets the eye and the T1 also has something to do with.

Try using TCP over the T1 link and see if that helps....
