FIX Resend Issue

Currently our prod env occur an issue about FIX Resend.
1) Before 03:31:16.621, our quickfixj was disconnected by upstream fix engine.
2) On 03:31:16.621, we re-connected.
3) On 03:31:16.839, we(CT) send Resend Request with tag7=23152 and tag16=0.
4) On 03:31:17.541, our customer returned from 23152 to 23974, then they send us 34=23977 and 34=23978, but SKIPPED 23975 and 23976.
5) I found our quickfix found 23974 and 23975 from its own memory queue at the same time, but not found 23976. So our sides occur 'MsgSeqNum too high, expecting 23976 but received 23977', cannot receive subsequent orders.
