NRE on ConnectionMultiplexer.WaitAllIgnoreErrors

[czd890]

Sometimes this error is caught on the server (out of hundreds of instances, 1-2 times every 2-3 days). I looked through the sourcecode and this NRE exception doesn't seem to be possible. 😢

Do you know if this is happening during shutdown, e.g. possibly a usage while the ConnectionMultiplexer is being disposed?
