ResendRequest: EndSeqNo is too low, how can we should interpret this message ?

Imported from previous forum

We’ve received ResendRequest with EndSeqNo < BeginSeqNo.

8=FIXT.1.1|9=39|35=2|49=FT59FIX01|56=FGW|34=3|7=2|16=1|10=007|

is it error ?

This should ideally be rejected since BeginSeqNo is greater than EndSeqNo – probably a session reject (35=3).
