RRS processing has detected a severe log stream error and the operator has responded COLDSTART to message ATR250E to request RRS to attempt to correct the problem internally. RRS internal processing has started to correct the problem. Message ATR253I will be issued when the processing is complete and RRS will resume normal processing. Should RRS fail to correct the problem, message ATR255E will be issued and RRS will be terminated. Messages ATR251I and ATR252I are the same. However ATR251I is issued to the operator console and ATR252I is written to the hardcopy log.
