[Quickfix-developers] Duplicate tag 9 on FIX 4.2 Message

[Vipula <vi...@ya...>]

Hi,
I'm using C# .NET 4.0 FIX 4.2  and sometimes my generated messages have duplicate tag 9 <BodyLength>. There for the CheckSum is invalid and the counterparty is rejecting the messages. This seems to happen when I try to send out a high volume of messages out. Other than that it is very random. Has anyone experienced a similar issue and appreciate any advice.

Thanks
Vips
