Inspect the capacitors on the board.  Most faulty capacitors can be visually identified by their blistered top.  Google faulty capacitor for images.

In pure circuit analysis you may have a faulty capacitor. Voltage leve ls rely on stable components when filtering AC sine waves to DC 9volts.

Component failure on the KVM board could cause a leak. Something shorting out on an op amp or one of the matrix switching driver chips. Pure conjecture on my part....

interesting trey.  what causes a voltage leak?  i discovered that its not the faulty server.  if i pushed any key while viewing any server, it rebooted all.  & occurred w/ greater consistency too.  kvm has a 9V ac power outlet which i unplugged but looks like its powered thru the kvm cable still, so i unplugged all servers & now its finally behaving well again.

 

no clue what causes it.  see that i have to truly reboot it to fix though.
