RE: [Quickfix-developers] problem with invalid PossDup=Y messages

Hugo,
We are seeing reports of this issue but I can't seem to replicate it with an
acceptance test. Can you post the logs that show this issue? I'll keep
trying to replicate it with a test.

Subject: [Quickfix-developers] problem with invalid PossDup=Y messages

Hi all,

I've detected a problem between quickfix server + client (or: acceptor +
initiator).
Let's suppose this rare scenario:

- client logs on;
- client detects seqnum gap, asks to resend messages from, say, seqnum=20;
- server resends message 20;
- (somehow message 20 has a tag without value, or some other validation
problem);
- client rejects message 20; (but does not increase targetseqnum)
- eventually, server sends next message;
- client detects seqnum gap, asks to resend messages from seqnum=20;
- server resends message 20;
- (etc, etc, client and server become stuck in this resend loop)


Versions affected (possibly not limited to) : 1.3.2, 1.7.0.

Am I doing something wrong / is this not true ?


Thanks in advance,
Hugo Leote
