The psinject process running on h1hwinj1 have stopped several times recently. The monit program on this machine then restarts the process and reports this to sysadmins. The latest stop-start was at 09:34 PST this morning, and I confirmed that the CW excitation was absent for 34 seconds at this time.

Here is a list of all the restarts for the month of November as reported by monit. Some may have been due to maintenance, and H1 may not have been in observation mode for every event.
