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

[<mic...@ba...>]

Unfortunately we cannot reproduce this issue in any of our test/development environments at all (regardless of the load, verifying corner case scenarios and etc). However we have seen about 5 such cases in production. It's a very tiny percentage of all cancel messages that had exactly the same format, (i.e. they did have the 447 tag), and that were parsed without any issue.  On a surface we see symptoms of a typical concurrency issue, which probably was caused by our approach how we use QuickFix.

Thanks
Michael
