{{Quickfixn}} Heart Beat Messages

[Amar Parmar]

Hi Andrew,
This is all in the same FIX session, so you do have a good point. The log out occurred just after the Broker had send a large number of messages to us. We sent a message to the broker 8 seconds prior to the log out.

Is the heartbeat only after x seconds of inactivity a quickfix setting or a part of the standard FIX protocol?

Thanks,

Is it all happening on the same FIX session?

My understanding is you don't heartbeat during lots of activity (i.e. you only heartbeat for x seconds without messages).

In that case, a message log excerpt around the droppage would be useful.  (A *real* log from QF, not something created by print statements in your callbacks.)

You're not trying to manually send or process Heartbeat messages, are you?  Sorry for the novice question, but I have to cover the bases.

Hi Grant,
Yes the connection is being logged out because the broker is claiming we did not respond to a heartbeat message within the required time.

What is your *actual* problem?  Is your connection breaking?  If not, then you don't have a problem.

I forget precisely how HBs work, because I never have to look at them.  The engine handles it for me, so I don't have to think about it.

Hi,

I seem to be having an issue with sending and receiving heartbeat messages when the fix engine is actively send and receiving messages.
In the *.messages.current.log file I see occasions where I am sending a heartbeat message but not receiving a reply and occasions where a heartbeat message is sent to me but I do not reply.

How are the heartbeat messages handled? Are they dealt with on a separate thread? Is there something obviously silly that I could be doing that could be blocking these messages?

Thanks,
