Crash in a service while being notified

[Thierry]

Hi,

I devellop a service in .Net/C# to configure / create a Wireless Access
point using Hosted Nework API.
I want also to be notified on suplicant connection / disconnection by
subscribing to hosted network related events (WlanRegisterNotification with
WlanNotificationSource.Hnwk).

All works but the service crash every 45 minutes.

Here is the windgb analyze; it's seems faulting code is
wlanapi!ClientRpcCallback.
Note that all the content of my notification callback is in a try/catch
scope, so 痣t's not supposed to crash in my code.

An idea about this issue ?
