Memory leaks for zrd when performing wide IP alias updating.


Memory leak after multiple wide IP alias create/update operations.


When an add, modification, or deletion of a GTM Wide IP Alias is made through the GUI or tmsh, there is a small memory leak in zrd. Although this memory leak is small for any one change, it could be noticeable after hundreds or thousands of changes when viewing memory consumption through 'top' or other tools.


If the zrd memory usage is negatively impacting system performance, you can restart zrd and clear out the memory usage by running the command: bigstart restart zrd.

Fix Information

Memory no longer leaks for zrd when performing wide IP alias updating.
