Re: [Quickfix-developers] Possible Bug w/ Duplicate SenderCompID's

[Jon D. <jd...@wi...>]

Oren,

I noticed the fix in CVS and was looking at it in a little more detail
and I was wondering if there was anyway an exception could be thrown
when unable to register the session - because there is already one
registered for that SenderCompID.

The reason being is, from an operational and troubleshooting standpoint
this could be a nightmare if you don't know why the connection was
dropped and the user simply states they can't connect to the Acceptor.

Reference(hope the link doesn't break):
http://cvs.sourceforge.net/viewcvs.py/quickfix/quickfix/src/C%2B%2B/SocketConnection.cpp?r1=1.8&r2=1.9

Thanks,
