Explanation

This Warning event indicates that the version store cannot grow because it is receiving out-of-memory errors from the operating system. The version store is where the Exchange Information Store service keeps records of transactions that are not yet finished. It is likely that a long-running transaction is preventing cleanup of the version store and causing it to increase in size. Updates to the database are rejected until long-running transactions are rolled back or deleted. When the version store is full, any updates to the database are rejected until the long-running transaction is completely committed or rolled back. This causes a service interruption for users.
