Memory leaks for zrd when performing multiple wide IP alias updating.


Memory leak after multiple wide IP alias updates.


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. This memory leak is not significant for any one change, but it might become noticeable after hundreds or thousands of changes when viewing memory consumption through 'top' or other tools.


Although there is no workaround, you can mitigate potential system performance impacts by restarting zrd, which clears out the memory usage. To do so, run the command: bigstart restart zrd.

Fix Information

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