Hardware Maintenance was notified and fixed the printer. IMPACT: Minimal. DOY 039 02/08/2010 S-ACE-0483 G10-0004 C&C Reboot Data capture statistics was being processed on ac1ws3. The weekly archive had not been purged in the previous week and the data capture statistics caused ac1ws3 to be out of memory. The automation software (C&C) was automatically rebooted and was running within 10 minutes. IMPACT: Minimal. No commanding was required during the 10 minute reboot.
