Cause


This problem has been reported in 2 bugs:

Bug 10397815 FREQUENT CORE DUMP GENERATED - SKGDBGCRA, KSDBGCRA, KSMLSGE_PHASEONE
Bug 10389708 MANY CORE_* DIRECTORIES CREATED UNDER THE GRID HOME'S DBS DIRECTORY

both bugs have been closed as duplicate of

Bug 9930490 MULTIPLE ISSUES IDENTIFIED WITH LISTENER METRIC TNSERRORS

where development explain that this can occur if TnsError listener metric is enabled from EM

Solution

1. Bug has been fixed in GC version 12. If possible please upgrade your grid control to 12g.
OR
2. As a workaround you can disable TnsError listener metric from EM GC Console.
