[Zope] ZSQLRelay Problem

[Evrim Ozcelik]

Hi,
My zope server is running on fedore core3. I want to connect to ms sql 
server running on windows xp platform using FreeTDS, SQLRelay and 
ZSqlRelayDA. My sqlrelay.conf can be seen below:

<?xml version="1.0"?>
<!DOCTYPE instances SYSTEM "sqlrelay.dtd">

<instances>
   <instance id="mssql" port="9000" socket="/tmp/examplesocket" 
dbase="freetds" connections="1" maxconnections="15" maxqueuelength="5" 
growby="1" ttl="60" endofsession="commit" sessiontimeout="600" 
runasuser="nobody" runasgroup="nobody" cursors="5" authtier="listener" 
handoff="reconnect" debug="none">
      <users>
         <user user="evrim" password="123456"/>
      </users>
      <connections>
         <connection connectionid="db1" 
string="sybase=/usr/local/etc/freetds.conf;user=evrim;password=123456;server=MyServer2k;db=LKSDB;" 
metric="1"/>
      </connections>
   </instance>
</instances>

As you seen there is only 1 listener socket created. I can execute the 
first sql command successfully but i can't execute the second command. 
The sqlrelay error shown in the log file:

Client Library error:
        severity(78)
        layer(0)
        origin(0)
        number(51)
Error:  Attempt to initiate a new SQL Server operation with results pending.

I think the connection does not end after the execution. When all the 
listener sockets used the system becomes useless. Then i restart the 
sqlrelay service in order to clear the sockets.

What must i do ? The listener socket must be empty after the execution.
