Something unusual has occured to cause the driver to fail

Hello,

I'm a it consultant and right now I'm involving in a Customer Care project.
A month ago we decide to use a Linux platform to support the database server
and adopt PostgreSQL as our database server. Last month we had the first
testing "experience". We were trying to simulate 100 concurrent users, but
when just 30 were connected we receive the following crash:
"Something unusual has occured to cause the driver to fail. Please report
this
exception: java.sql.SQLException: Sorry, too many clients already
at org.postgresql.Driver.connect(Driver.java:125)
at java.sql.DriverManager.getConnection(DriverManager.java:517)
at java.sql.DriverManager.getConnection(DriverManager.java:177)
at DbManager.connect(DbManager.java:35)
at Hilo.<init>(TheFrame.java:242)
at TheFrame.main(TheFrame.java:181)"

If it means that PostgreSQL doesn't support more that 30 concurrent users
unfortunately we would have to migrate our current development to another
database server, such as MySQL or Oracle. But if, as I suppose, this is just
a JDBC driver's bug we would like to know if another "free-bug" driver is
available.

This is critical for us, so please, reply me as soon as possible.

Thank you,
Juan José Antolínez
