Evan, Jim W, Dave:
h1nds1 locked up this afternoon at 14:36PDT. Jim manually reset the computer around 19:00PDT, but monit failed to autostart the daqd process. I logged in as root and restarted monit, whereupon it correctly started daqd. We have seen this "monit at reboot time" failure before.
This initial problem occured at 14:36 PDT, a swapper page allocation failure. Details attached.
