odbc error : multiple connections at once

[ss]

Dear All,

I use ODBC to connect php (installed on linux) to a MS SQL Server 2000
database. I use iODBC and Freetds.

Everything looks fine, until I try to open a multiple connection at
once to the SQL server (I didn't close a connection before I opened a
new one). I've got an error with strange characters :
Warning: SQL error: ä , SQL state l ýÿÿÿ in SQLExecDirect in
.....

I try to connect using "odbc_conne ct" and "odbc_pconnect" , and both of
them give me the same error. If I close the previous connection before
opening a new one, everything goes well.

Unfortunately I need to open multiple connections at once. What can I
do to solve this problem?

Thanks in advance.

IG.
