System.Net.WebException (Build2879)

[TJIMH]

seeing a fair number of the client side exceptions shown below. what might this be indicative of:

System.AggregateException: One or more errors occurred. ---> System.Net.WebException: The remote server returned an error: (500) Internal Server Error.

Not sure I know how to find the actual error? That is what is being logged when the app crashes??

Check the event viewer on the server that is running ravendb.

[TJIMH]

What I see in the event log at the time of the error is an initial TaskCanceledException - A task was canceled

Then their are Information events indicating from ESENT saying the database engine stopped the instance.

Then there are a couple of errors:

An unhandled exception occurred and the process was terminated.
