The CMManager constantly get called every few seconds using bearer management

STEPS TO REPRODUCE:
1. Start bearer enabled 8.x Browser
2. tail -f %TEMP%\epocwind.out
3. Observe CMManager traces every few seconds
ACTUAL RESULTS:

EXPECTED RESULTS:
There is no network configuration changes, so there is no need to update all the time.

You can also set breakpoint (W:\sf\mw\ipconnmgmt\cmmanager\cmmgr\Framework\Src\cmmanager.cpp [line: 329]) in carbide to catch the stack trace.

Further analysis indicate that the RDbNotifier::ERollback event is called again and again in void QNetworkConfigurationManagerPrivate::RunL(). The event is casted from iStatus.Int().
There is no change in the value of iStatus from several runs/catches.
