{{Quickfixn}} How to logoff? FileLog error: System.ObjectDisposedException

[Grant Birchmeier]

Looks like we might have some kind of timing condition here.  Every
instance of FileLog should only be disposed once.  It's apparently
happening twice.

Does it always happen on the second time you call Stop()?
