APAR status
Closed as program error.
Error description
The issue only happens on encrypted databases. In rare cases, asynchronous page-cleaner agents might incorrectly flush modified pages to disk before the corresponding log records have been flushed to disk. This is in violation of Db2's write-ahead logging protocol. If a database crash occurs while a page has a change on disk whose corresponding log record is not on disk, then the subsequent crash recovery might fail or it might complete successfully while leaving database objects in an inconsistent state. This might result in a wide variety of errors or might cause Db2 to return incorrect results.
Local fix
Run db2dart or INPSECT to examine the database after running crash recovery on an encrypted database. To turn encrypted database to un-encrypted can be done by restore.
