Comment 6 for bug 1581581

I tried something new yesterday when problem happened again. This is what I did:

-- With Epoptes tool I shut down all of the computers that were showing in the 'detected clients' window.
-- Computer "9A" wouldn't shut down, remaining in the detected clients window.
-- I went over to the client to check it out and saw that the small green power light on the computer was on, however, even though the display should therefore have been on, it was dark.
-- I checked the logs for previous few days and nothing unusual about that client, just 3 very ordinary entries.
-- I had tail command on the epoptes log as I powered down the client (client is 192.168.67.175)...

:~$ tail -f /var/log/epoptes.log

... as the client disappeared from the detected clients window.

This is the first time I've seen anything out of the ordinary in the epoptes logs. Not sure if this is relevant. Anywhere else I should check? I do have other epoptes log results from a week ago but as I mentioned, it doesn't look like there's anything out of the ordinary. It probably won't happen again as school's almost over for the year. Let me know any other place to check, I've got times to check in other logs. Thanks!
