WLC Wism2 memory usage doubled

[Eric Lindsey]

We have two Wism2 controllers running 7.3.10 and in the last 30 days they have both doubled the memory usage on the controllers. They went from 26% usage to 51% usage. Is there a way to figure out what may have caused this increase in memory usage and is there any concern? We have not had any major changes or additions to our controllers.

You might have IPv6 enabled.  

Besides, who'd still want to use 7.3.X.X?  Upgrade to 7.4.121.X as it's widely considered to be more reliable and stable.

We have a 3550 appliance stuck at 7.3 right now. We just bought the virtual Mse license and are getting ready to move over to it. We have 7.4.121 ready for the Mse since it is compatible with the other pieces of our wireless network.  Then we can upgrade prime, wlc, etc.
