RE: [Quickfix-developers] Logon-Mystery Disconnect

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

Thanks for the suggestion, but I don't think it's that.  I destroy my  =
FIX Application, Session, Log, etc objects and remove the logs on a =
nightly basis, so unless there's an initialization problem when these =
objects are created, I am pretty certain my sequence numbers are coming =
up 1,1 in the morning.  In the example below he comes in at SeqNum=3D1 =
and is disconnected.  4 minutes later he comes in at 2 and is allowed to =
log on, however qf logs that it expected SeqNum=3D1, received 2.  So it =
does not look to be a too low seq num issue.  Not to beat a dead horse, =
but again, adding a reason indicator to the "Disconnecting" message =
would go a long way to clearing up, if nothing else, at least why qf =
thinks it should be disconnecting the session.

This sounds like he may be logging in with a sequence number that is too =
low.  What will happen is he will attempt logons, get disconnected due =
to the sequence number being to low.  Every time he is sending a logon, =
he increments his sequence number until he eventually reaches the right =
one.  Perhaps yor sequence numbers arn't being reset when you think they =
are?

Yes.  The enigmatic "Disconnecting" especially.  This morning I observed =
a repeat of the exact same behaviour as yesterday.  The client attempts =
the logon at 12:05 gmt is disconnected for reasons that I cannot fathom =
from the logs, and then successfully reconnects and logs on 4 minutes =
later.  If anyone has experience/insight into this, it would be greatly =
appreciated.

Yes, QF could be a lot more verbose in the event log, esp. for the=20
following cases:

1. Rejected logon
2. Disconnect
3. Logout with user provided logout reason
4. Dropped messages fragments which fail body length or CRC check.

Cheers, J=F6rg
