c# - QuickFix/n multiple Session on the same port -

should able run multiple session on same port in quickfix/n?

i have following config

[default] connectiontype=acceptor reconnectinterval=2 filestorepath=store filelogpath=fixlog persistmessages=n starttime=00:00:00 endtime=00:00:00 logouttimeout=5 resetonlogon=y usedatadictionary=y validatefieldsoutoforder=n allowunknownmsgfields=y validateuserdefinedfields=n validatefieldshavevalues=n appdatadictionary=config/fix/fix50sp2.xml transportdatadictionary=config/fix/fixt11.xml beginstring=fixt.1.1 defaultapplverid=fix.5.0sp2 heartbtint=30 sendercompid=mercuria sendersubid=1 socketacceptport=5011 [session] targetcompid=client1 socketacceptport=5011 targetsubid=1 heartbtint=30 [session] targetcompid=client1 socketacceptport=5011 targetsubid=2 heartbtint=30 [session] targetcompid=client1 socketacceptport=5011 targetsubid=3 heartbtint=30 

but when run , logon client 1 subid of 1 "an existing connection forcibly closed remote host" error.

this works alright if change session config have different send compids so:

[session] targetcompid=client1 socketacceptport=5011 heartbtint=30 [session] targetcompid=client2 socketacceptport=5011 heartbtint=30 

is config valid i.e. using multiple session on same port same comp id differing sender/target subid?

thanks, nick

an acceptor can accept multiple connections on same port, must have unique targetcompids.
