OpenMarkup is a log of how the ZCB user interface (UI) interacts with the Java Runtime Environment. It is built grows in size only when the UI is interacting with Java. This log is included when the Send Logs option is used, and can be useful for troubleshooting purposes. In other words, OpenMarkup only grows in size while the UI is open and operations are performed.
If the UI is left open for a long period of time, the OpenMarkup log can become very large.
This log is included when logs are collected using the Send Logs option. It can be useful for troubleshooting purposes.
Do not leave the user interface open for a long period of time, especially on the Monitor page. There is no need to leave the UI open unless it is actively in use. All operations, such as Backup or Restore, will continue to run even if the UI is closed.
Also, Openmarkup is deleted each time the UI is opened. If the log becomes too large, simply close the UI and restart it.
