FileStore for initiator resetting sequence number

Created by: lkcole

I am using FileStoreFactory for managing 1 session where the ResetOn* configuration settings are unset (they all default to N).

Upon receiving a message from the acceptor to set my sequence number, I stopped the application. After I was sure the process was down, I modified the senderseqnums file associated with the session to the one specified by the acceptor and save. I verified the file was correct and of the appropriate permissions (640). Upon restarting the application, the sequence number populated by the engine was 1 AGAIN. The senderseqnums reflects the same thing.

I've walked through the FileStore.go logic as well as the session.go logic and can't figure out why it would reset. And if it does reset, there should be an event generated.

This appears to be a bug or something glaringly obvious that I'm missing. The pertinent log is below. Any help in resolving this issue would be greatly appreciated.
