[Quickfixj-users] Problem with ResetOnLogon flag

[Paul N. <pau...@be...>]

The ResetOnLogon flag in the config is a really handy way of resetting
sequence numbers when they have gone badly out of sync. However, there
is a problem with it. Consider this scenario:

 

Sequence numbers are out of sync

1. Add ResetOnLogon=Y to config file

2. Restart your quickfix server

 

Later on there is a problem with the target machine

1. They log you off and log you back on again

At this point the ResetOnLogin flag IS STILL ON and sequence numbers are
then reset back to 1 when you log back on

 

Now there is a real danger that any messages held in the message queue
are resent. Normally they would be rejected as duplicates by the target.
However, because we've reset the session they aren't seen as duplicates
because it's a new session and go in as NEW trades.

 

Ideally this flag should only be applied once. Has anyone else
encountered similar problems with this flag? Are there any workarounds?

 

I was thinking of removing the tag from the logon message if its been
sent once already.

 

Paul
