[j-nsp] Fwd: Cable need to unplug/plug after box restarted

[Sean Clarke]

When the circuit is up, try and rapid ping end to end - is the ping 
continuously okay ?
if it keeps stopping at regular intervals perhaps you have clock slip.

If the clocksource is good, I don't understand why you see this issue.

Did you open a jtac case ?

cheers
Sean
