Keep alive entries are used to prevent skipped updates from being evaluated several times in a fractional replication. If a large number of updates is skipped, these entries can be updated very frequently. Before the keep alive entries are updated, it is tested that they exist. Previously, the test was being logged at a "Fatal" log level, so it was always logged no matter which log level had been set. As a consequence, error logs were filled with unnecessary messages. With this update, the log level for keep alive entry creation has been changed from "Fatal" to "Replication debugging" (8192), and the error log file is no longer filled with "Fatal" messages.
