I've seen few errors as below in series. Are these something I need to consider as Priority???
May I know what exactly is FFDC mean? and How this can be used????
a part of the answer is in the question: FFDC is "First Failure Data Capture"
and yes, you should treat this as priority, collect supportsave and open the case with your support provider
In addition to Alexey post, Usually these messages appear as a consequence of some previous failure, normally a switch daemon that fails. Depending of the deaemon, it could be more or less critical and most of the times a FOS ugprade fixes it.
