[Quickfix-developers] Valid resend requests rejected by QuickFIX library

[gunnar <gh...@hi...>]

Hello,

We have some problems where our FIX server (an acceptor) sometimes 
rejects perfectly valid resend request messages from our clients.
In the event log we then see for example:

20140225-08:04:51.589 : Received ResendRequest FROM: 3356 TO: 3374
20140225-08:04:51.589 : Invalid message: Header fields out of order

(or it can complain about no SOH at the end. In any way QuickFIX is 
wrong because the messages that we receive are valid 35=2 messages)

We use the C++ QuickFIX library.
The issue is not easily reproducible and happens rarely, twice a month 
or so. If it happens we restart our FIX server and from then it accepts 
the exact same resend requests again.
I know I have not provided much information in this email, but am just 
hoping someone recognizes the issue.


Regards,
Gunnar
