Had a problem yesterday where one cpu (cpu 0) on an ESX Host was piked at 95 - 100%. Ran top and found that ftPerl was using 79-80% cpu. Thought it was something on a VM but all the VMs were using average cpu. Found something on the internet indicating it was HA. Ran a "Reconfigure HA" on the problem host and the process ended. The host then returned to normal. Is this a known issue?
