Why won't CSCus46997 be fixed?
A memory leak bug, with the work around being to disable macros entirely? huh? Anyone know why cisco wouldn't fix this bug? This has been affecting us for months now. We have to reboot the stack weekly which is very annoying. Otherwise the console is unusable with the lag and pings are failing all over the place when its in this state. Anyone know why this is marked as &quot;status terminated&quot; and &quot;no releases planned to fix&quot;?? huh? https://bst.cloudapps.cisco.com/bugsearch/bug/CSCus46997/?referring_site=bugquickviewredir ...
