[Quickfix-developers] Already sent ResendRequest ... Not sending another.

[Scott H. <sco...@fo...>]

Has anyone encountered problems with the code that was added between 1.9.4 
and 1.10.2 that emits the "Not sending another" message?  Oren's CVS 
comment was "fix for stack over flow with recursive next calls. Do not 
resend if request already exists with same range.  Submitted by Caleb 
Epstein."  Note that I'm using QuickFIX/J, but the C++ code is the same.

My session started out normally, but (possibly due to an unrelated bug in 
QFJ socket input) somehow loses a message (#216250) and should have tried 
to get the counterparty to resend it.  But due to an earlier (successful) 
ResendRequest, the "Not sending another" code kicks in repeatedly (a very 
bad failure mode -- app gets no new messages yet session appears 
functional).

I see two fixes:
(1) modify nextSequenceReset() to call state.setResendRange(0,0)
(2) modify the range check in doTargetTooHigh()

Any advice?  See my events below.  The message length error was emitted by 
quickfix.netty.FIXMessageData.read().
