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

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

Hi
Could you advise on the following issue, please?
We receive intermittent "Required Tag Missing" error while parsing incoming fix messages, even though the missing field is present in the message. For example in the following message the tag 447 is present on the message, and yet sometimes we receive "Required Tag Missing, field=447" while parsing it.
8=FIX.4.4|9=284|35=F|49=TEST_49|56=TEST_56|34=420|52=20190302-07:31:57.079|115=TEST3|116=TEST_116|11=TEST_11|41=TEST_41|55=TEST_55|48=TEST_48|22=4|54=2|60=20190302-07:31:56.933|38=TEST_38|207=TEST_207|454=3|455=TEST_455_1|456=TEST_456_1|455=TEST_455_2|456=TEST_456_2|455=TEST_455_3|456=TEST_456_3|453=1|448=TEST_448|447=D|452=3|10=XXX|
This issue has been observed with cancel messages and it normally happens after application startup. We do use a data dictionary, and 99.8% of the time such cancellation messages work fine. We use quick fix version 1.5.3. (quickfixj-core-1.5.3.jar and quickfixj-msg-fix44-1.5.3.jar)
Are there any know issues with intermittent "Required tag missing" errors?

I'd also created the  https://www.quickfixj.org/jira/browse/QFJ-971 JIRA for this question as I was not sure if it falls into the "help" or "error" category.

Many thanks and Kind Regards
Michael
