[Quickfix-developers] Duplicate logon attempt handling

[Howard E. <ho...@ex...>]

Testing my fix server under the following circumstances seems to put
quickfix into an erratic state.

A user logons on with a SessionId (FIX.4.2:SBI0->SLGM0) and sends in
some orders.

Then that users starts a second logon with the same SessionID.

I never see this second Logon attempt in my App class's fromAdmin or
onLogon overrides,
however, my App class does receive the onLogout event twice (both times
with the same SessionID).

Furthermore, the second session is disconnected, however I continue to
see heartbeats being received 
from the User's First fix client in the FIX incoming log, however I do
not receive these in the 
fromAdmin override, and I do not see anything in my FIX outgoing log.

Ideally, in this situation, if I receive a Logon Request for a Session
that I currently belive to be alive, I 
would like to drop the first session, and then handle the LogonRequest. 
If not that, then I'd at least like to be
able to Reject the second logon attempt.  However, since I never receive
the fromAdmin it doesn't seem like
there's anything I can do either way.

Any help would be appreciated.

Thanks,
