Re: [Quickfixj-users] Sequence number too low vs Sequence number expecting?

[Christoph J. <chr...@ma...>]

My question:

again, do I understand this correctly? You are saying that for some types of messages with too low a 
seqnum you do NOT get logged out?
Can you paste some example messages that you sent/received?

Cheers,
Chris.
