We are tracking occassional timing errors on h1ioplsc0 which started following its restart yesterday morning when we modified h1lsc to add a DQ channel.
From that restart to now (22 hours) we have had 9 timing errors, of which 3 caused IPC receive errors on h1omcpi.
This had been seen before, in the 09dec2025 - 15dec2025 time period and appears to be related to restarts of the IOP, not code changes.
We don't think this will impact locking activities, we will keep investigating.
I'm running a python script which clears h1ioplsc0 TIM error if that is the only error in STATEWORD. It also clears h1omcpi's IPC Rx error if needed. It runs every minute.
