MAP 0210: Intermittent failures
Symptom explanation
Intermittent Failures
General information
All possible indications and symptoms should be recorded to aid you in using this MAP. System error logs, when
available, aid in identifying intermittent problems. Obtain all information concerning the failure from operator
system aids and information:
v Error/Status codes - displayed on operator panel
v System error log - host system information
v Online problem - operator identified
v System identified problem
v Power on failure - cold start
v Long run - time failures - hot, overheated
An online program can be used to find intermittent failures. Ask the operator to run the failing job for you to
observe, if possible.
