Explanation: Read encountered a modified block.
Possible Cause: A read operation encountered a block in the database that was being modified by another user. The read is unable to continue because transaction logging has been disabled for the database.
Action: Perform the operation again. This is a temporary condition and will generally correct itself. As a general rule, transaction logging should never be disabled on GroupWise databases.
Action: If transaction logging has been disabled on the database, the only way to re-enable it is to rebuild the database. See "Maintaining Domain and Post Office Databases" and "Maintaining User/Resource and Message Databases" in "Databases" in the GroupWise 6.5 Administration Guide.
