RE: [Quickfix-developers] Heartbeat

Joerg,

I don't have the logs with me anymore and will need some effort to recreate=
 it. Basically, it happens when we evaluate the QF engine by sending large =
amount of messages without throttle from an initiator to an acceptor. The i=
nitiator will miss the heart beat after a certain period of time, and then =
it sends the test request to force a heart beat. After that miss it declare=
s the session down by log off.

Yihu, can you send us log files showing the same scenario using=20
SocketAcceptor and ThreadedSocketAcceptor?

Could you please send log file (from both sides of the connecting FIX=20
engines if possible) to have a more detailed look at this?
