[Quickfixj-users] Spurious Resend Request

[Starkie, M. <mst...@aq...>]

Hi,
I'm seeing strange behavior where my initiator seems to think it's missing a message and transmits a Resend Request to the acceptor.  The QuickFix logs show I received message 1744 on the Message processor thread:

2018-04-24 13:49:24.109 [20962108][QFJ Message Processor][INFO ] Received MessageMap[10=170, ..., 34=1744, ...9=362] [Phase3Gateway.java:218]

but then the same thread immediately complains it didn't receive msg number 1744

2018-04-24 13:49:24.109 [20962108][QFJ Message Processor][ERROR] FIX.4.2: MsgSeqNum too high, expecting 1744 but received 1745: 8=FIX.4.2^A9=362 ... ^A34=1745 ... ^A10=153^A [SLF4JLog.java:147]

I'm using:
quickfixj-all-1.5.3.jar

Could it be that I have too much business logic on the QFJ Message Processor Thread and it's taking too long to complete?
