Several CDMP Directories are created when errorstack event is set, e.g:

The cdmp directories have KST traces for all the DB processes and not just the process which encounters the error. The Error message in the alert log may show "summary=[abnormal process termination]" while the process would still be alive.

During multiple occurrences of the error, lots of cdmp directories are created. This fills up the filesystem and the Database is impacted.
