18.7. Recover data from orphaned diskbuffer files
When you change the configuration of a syslog-ng OSE host that uses disk-based buffering (also called disk queue), syslog-ng OSE may start new disk buffer files for the destinations that you have changed. In such case, syslog-ng OSE abandons the old disk queue files. If there were unsent log messages in the disk queue files, these messages remain in the disk queue files, and will not be sent to the destinations.
