Trying to pick up after a nework failure the quickfixj engine is logging out after each resend request.
The reconnection interval is set to 15 seconds in the config file.
See log example below where a syncronisation of approx. 3 messages is done before logging out and then waiting 15 seconds(reconnection interval) for logging in again.
In this case the initiator missed 280(heartbeat) seq.no which took more than 20 minutes to syncronize.
