Re: [Quickfixj-users] Intermittently we receive the "Required Tag Missing" error for existing fields

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

Hi,

unfortunately I do not have a solution but also did see such problems with a client of ours and it 
was also the exact same tag 447 that was the problem (although another message type). The 
application was already running for several hours.
We also could not reproduce it. It just appeared once every few months... :-/

Cheers,
Chris.
