Frequent Watchdog failure
Posted: 12 Sep 2021, 04:09
UaExpert: 1.5.1
UA Client SDK:3.0.9
I getting frequent disconnection trigged by WatchdogTimeout as per below log.. I am not sure why it is frequent ?
In some cases it is being recovered by reconnect and refresh.
Any idea why getting "Cannot access a disposed object.
Object name: 'TapTcpConnection" and what it means . Is session disconnected ?
