After upgrading Version 7.0 To version 7.4.121
Errors similar to the following are logged:
[ERROR] ewmain.c 5379: emweb internal error - handle not in Handle table
[ERROR] ewmain.c 2931: EmWeb: Handle table overflow @2931
At the same time, end clients are not able to hit web-redirect page. The page would either error out or client sees the virtual IP address in address bar.
Or, browser connection attempts to the WLC GUI time out.
