At 12:58:31 PST the IOP for h1susey took 69uS for a single cycle which in turn caused a single IPC receive error on h1iscey. This TIM error has been occuring approx once a week for EY, in this case it is the IPC error which is unusual. We should clear these accumulated errors the next time we are not in observation mode or during Tuesday maintenance, whichever is the soonest.
