Oh, OK. Sounds like Justin has a memory leak issue with 4.2.176

4.2.130
CSCsx07878—Client devices no longer intermittently fail to log into
a WLAN with web authentication (webauth). This one broke us in
4.2.176. We are using the internal web re-direct for
authentication. This does not work properly in 4.2.176.

The fix for this is in 4.2.205.
Sorry for the confusion.
