java.sql.SQLNonTransientException: Instance has too many concurrent requests: 100

we have built  a benchmark [tpc c] and simulator under a Google Research grant.

the benchmark [a client python program] generates the following number of concurrent users

[accepted by a frontend java program(multiple instances) that sends SQL statements to CloudSQL database instances of varying sizes]:

number of concurrent users:

10,

20,

40,

160,

320,

1,200,

7,500    

the  frontend java program uses: 

1. conn = DriverManager.getConnection("jdbc:google:rdbms://instance:xxxxx/tpcc32")

2. conn.prepareStatements

3. xxxxxxx.executeUpdate()   AND

4. yyyyyy.executeQuery()

to communicate with the CloudSQL instance

thanks for your help
