[Quickfix-users] Sequence number resets question

[Radhika S. <Rad...@Pi...>]

Hi,
=20
I need some help with message sequence numbers not being set correctly
by the fix client.
The client I am writing uses a fix session to connect to the server.
Every time I logoff, I issue a session.logoff() - which according to the
docs says resets sequence numbers.
The behavior I am facing is that every time I logon using the same fix
session, the client sends the last used sequence number.
A very first time login (even though last used sequence numbers are
sent, and then a message sequence number of 1 is sent) is successful.
Logging off and re-logging on creates a mis-match in the session
numbers.
The server seems to be resetting and asking for a sequence number of 1.
The client seems to be providing a larger number.
Any ideas or help on this will be helpful. I have included both Client
and Server event logs below.
Thank you.
Radhika
