Description

Seen in a log file:

27.05.2015 11:34:48.130 *WARN* [DocumentNodeStore background update thread] org.apache.jackrabbit.oak.plugins.document.DocumentNodeStore Background operation failed: org.apache.jackrabbit.oak.plugins.document.DocumentStoreException: com.ibm.db2.jcc.am.SqlTransactionRollbackException: DB2 SQL Error: SQLCODE=-911, SQLSTATE=40001, SQLERRMC=68, DRIVER=3.65.77
org.apache.jackrabbit.oak.plugins.document.DocumentStoreException: com.ibm.db2.jcc.am.SqlTransactionRollbackException: DB2 SQL Error: SQLCODE=-911, SQLSTATE=40001, SQLERRMC=68, DRIVER=3.65.77

We need to decide whether these are harmless in that the operation will be repeated anyway. If the answer is yes, we may want to tune the log message. If the answer is no, we need to dig deeper.
