We restarted the psinject CW hardware injections on h1hwinj1 last Wed 11th to see how stable this system is now. All was well until yesterday (Thu) when it stopped running for no discernable reason. Here is a summary:
date | time | event |
wed 11 May | 14:11 PDT | start running psinject |
Tue 17 May | 08:32 - 08:38 PDT | stopped due to h1iscex restart, manually restarted |
Wed 18 May | 10:03 - 10:04 PDT | Jim manually restarted process |
Thr 19 May | 14:20 PDT | psinect stopped for no apparent reason |
We were not running under monit control so that a restart would be easy to spot. Now we have seen a restart, we'll put psinject back under monit control. Remember that the monit script smoothly ramps up the injection to prevent jarring.
actually the psinject process was still running on h1hwinj1, but it was not actually exciting the test point H1:CAL-PINJX_CW_EXC. I started monit, and then used monit to stop the running process and perform a clean start.
