Re: [Quickfixj-users] How are resend requests handled after logon?

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

Hi,

it is not uncommon that old (resent) messages can be interleaved with new ones. All messages which 
have too high a seqnum need to be queued until the ResendRequest has been satisfied.
Without browsing all closed issues since version 1.5.2 I could imagine that there *might* be a bug 
which does not handle this correctly. But to be really sure I guess I would need some more 
information like message logs.

You had a similar issue back in September where I thought it could be related to 
https://www.quickfixj.org/jira/browse/QFJ-673 . But maybe it only sounds like it is the same issue.

Cheers,
Chris.
