This error is generally raised by the log reader agent while running transactional replications. The error indicates that distributor and subscribe databases has data that may be more recent than data in the publisher database (the agent compares latest LSN in transaction logs of Publisher database and latest LSN recorded in the distributer).
This problem usually occurs after publisher database has been restored from a backup.
To resolve the issue, run sp_replrestart stored procedure in the publisher database and then reinitialize the subscribers. Also, consider running DBCC CHECKDB on publisher database to validate consistency.
