The SessionQualifier was introduced -- if I recollect correctly -- to all=
ow QF to manage=20
several sessions with same SenderCompID and TargetCompID, _but_ different=
 accept ports.

Before that a QF session was uniquely identified by (BeginString, SenderC=
ompID, TargetCompID).

The important point in your case is that the SessionQualifier is _not_ tr=
ansmitted over=20
the wire, ie if both of your initiator clients has a different SessionQua=
lifier=20
configured, but connect to the _same_ port with identical (BeginString, S=
enderCompID,=20
TargetCompID), QF will forward these requests to the _same_ session, whic=
h results in the=20
disconnects (since the session is already logged on).

Please try with different ports for each different qualifier.
