Crystal Reports return Error 534: Error Detected By Database DLL


I'm using Crystal reports 8.0 with Sybase 7.0 on Win 2K/ NT system using ODBC connection.
When I run two reports simaltaneously it returns "Erro 534: Error Detected by Database DLL"
This error does not occur all the time. I've tried ODBC tracing, I found some errors:

 Cons            1184-1340      EXIT  SQLSetConnectAttr  with return code -1 (SQL_ERROR)
            SQLHDBC             01D71590
