MOS关于该问题记录
问题原因

This is due to Bug 9390347 fixed in 12.1 & 11.2.0.2, where a core dump can occur 
in module dbgrmqmqpk_query_pick_key() whilst purging HM contents from ADR.

解决方案

- Either install our 11.2.0.2 patchset
- Or download and apply Patch 9390347 if available for your version/platform.
- On Windows, you can also install Bundle Patch 11.1.0.7.31 or above.
There is no workaround to this error, however the error is not serious and does not cause any harm to your database.
