Thing is i have the DB2 V8.1 cd uploaded to an nfs share. If i export
from an older aix box (same version and ML - by older i mean installed
a few months).

Im loading the application from the same location on both servers.
Port 7100 is open on the xserver (as tcp - udp doesnt seem to be
open).

So why would it accept fonts from one and not the other? Doing a
netstat -an on both exporting servers, they are connecting to ports
2049 & 6001 under tcp4 (so the fonts running over udp doesnt seem to
be an issue).

However,, when i have the performance meter on the desktop of the
xserver, when i load from the machine thats messed up i see a wild
fluctation in packets abd interruprts, as well as the CPU spiking.
When i go from another machine, everything just seems steady.

i there a way to investigate this further?
