hi team, We had an issue recently wherein there was a disconnection on the acceptor side. The initiator rightly failed over to the second host and sent a resend request, which was fulfilled by the server as well. The instability persisted and we noticed multiple resend requests were sent in between. What we noticed though, during the time the application was catering to processing re-sent messages, when new messages were coming in at the same time they were getting queued up. We saw lines like below in the events logs: MsgSeqNum too high expecting <> but received <> .... Enqueued at pos: <num> In ideal scenarios, which I can see for certain messages in the beginning, we see log like this: Processing queued message: <num> But we do not see this happening for the majority of these new trade messages causing the messages to be eventually missed. We are on quickfix all version 2.3.0. Would anyone have seen such an issue and can opine what could have happened? Regards, Ankit |
