GNUGK BUG ?? Version(2.2.4)

Hi

I am running the gnugk following version

Gatekeeper(GNU) Version(2.2.4) Ext(pthreads=1,radius=1,mysql=1,pgsql=1,large_fdset=0) Build(Jun 29 2006, 21:24:02) Sys(Linux i686 2.6.11-1.1369_FC4smp)
GkStatus: Version(2.0) Ext()
Toolkit: Version(1.0) Ext(basic)

The problem I have is there are calls trying to connect on certain routes which is more than the defined number of ports. eg – Quintum 24 port… it attempts about 30 calls and keeps dropping and return cause code 34.

May I know any clue for the cause or this
