What to do when the ccd gui freezes Last updated: Eric Hsiao, Feb 6, 2012 *Symptoms* The data pc sometimes run out of memory and require reboot. The symptoms are frozen ccd gui (camera control window) or frozen guider window or both. Killing and restarting the gui will give you an error message like: Fail to connect to private2.lco.cl *Solution* In a command comm window on SPARC (from the screen on the light blue rack, switch to the third screen we never use), try "ping pc". If it does not respond or gives a time out, then there is nothing to do but a hard reset by switching the pc off and on. If it responds, type telnet pc username: *check paper taped on side of light blue rack* passwd: *check paper taped on side of light blue rack* reboot pc
