Multithreaded operations on remote Gem with encrypted extents corrupts cache

When a remote Gem (a Gem not on the Stone's host) is logged into a repository with encrypted extents, executing a multithreaded scan operation in the remote Gem may cause cache corruption. The operation may report errors such as " An error occurred during a multi-threaded operation: 'Page Locate failed for pageId N"; and the Stone may shut down.

Multi-threaded scan operations include listInstances, allReferences, markForCollection, and related operations.

Workaround

Do not executed multithreaded operations on remote Gems with encrypted extents.

If you do, and see PageLocate and similar errors, shut down the Stone. It is recommended to run pageaudit, restart the Stone and run objectAudit.
