Commit or roll back orphaned transactions to avoid filling up the inbound queue.
An orphaned transaction is a transaction in an inbound stable
queue that is missing a terminating
commit or
rollback command.
Because Replication Server does not free up a queue segment until
every transaction in the queue segment (or in any of the preceding
queue segments) has been committed or rolled back, orphaned transactions
can cause the inbound queue to fill up.
