Redis: Poll now - unhandled exception

[win32nipuh]

My opserver configuration contains: 4 sql servers and 2 redis servers.

1. Go to 'Redis'
2. Click 'Poll now' 3.Visual Studio Just-In-Time Debigger appears: An unhandled Microsoft .NET Framework exception occured in w3wp.exe

Btw, checked the same for SQL Servers - it works ok.

The Event Log record:

An unhandled exception occurred and the process was terminated. Application ID: /LM/W3SVC/1/ROOT/opserver Process ID: 30160 Exception: System.NullReferenceException Message: Object reference not set to an instance of an object.

I've seen this as well

I was finally able to reproduce this in our production environment, should have a fix in the next commit. It's part of a very large async overhaul simplifying how polling in general works.

Great, thanks

Closing this out, no longer an issue.
