GI 19.31 and 19.32: trace file flooding in mgmtca.trc can happen

Thanks to Peter Lehmann who always alerts me about findings and encounters he had in his test and production RAC cluster environments. Peter dropped me an email the other day, and I share his suspicion that this may effect many in the coming weeks operating RAC environments. If you don’t have a RAC, you may not see this happening with GI 19.31 and 19.32: trace file flooding in mgmtca.trc can happen.
