Every 13weeks + 1 day I receive 4 heapdumps(in few hours, below list of files)

I cannot see any scheduled task/job with such time-frame the same story on 3 nodes(set by the same person)

How or where I can check to know what it does, before open a service request with Oracle? using vi or em?

TIA

oracle version 11.1.0.7.0 (without any patches since ~2010)
