When Notes
20130325 first noted


Sequence: a,E,o,c => Camera is cooled and working, and we get frames. We stop during for a couple of hours during a videoconf (S,C) but camera is kept cold

We restart (c,s). We don't get any frame. 'L' shows problems. The log of wfsServer shows problems.

See the full email thread: Gmail_-_Camera_doesnt_restart_after_a_pause.pdf

The voltages applied to the camera are wrong: Screenshot-7.png

See also log_inaf_pnccd_pc_service.txt: log of wfsService from 20 to 25 March


When wfsService is restarted on the pnccd_pc the camera is back in operation. See the email: Gmail_-_Camera_doesnt_restart_after_a_pause.pdf

Try to reproduce it asap.


The memory leak that caused the server to crash was identified and fixed in a couple of weeks.
