DRAC session looses keyboard connections

Dear All,

I was wondering if any of you have previously noticed that a DRAC
console sometimes looses the remote keyboard connectivity?

I can mount an ISO image and deploy a machine through the console, but
at some point the DRAC console looses the connectivity with my keyboard
and I can no longer do anything. Not even (Linux) switch to alternate
TTYs. Only a ctrl-alt-del through the DRAC menu works, only to loose
connectivity again a few minutes later.

Any ideas?
Chris.
