Postgresql driver Question

Hi All,

We are performing intensive stress test of C-JDBC on top of a cluster of
4 postgresql servers.

During a run, one of the insert request was blocked in the postgresql
JDBC driver (latest version ...)

Here is the stack trace:
        at java.net.SocketInputStream.socketRead0(Native Method)
        at java.net.SocketInputStream.read(SocketInputStream.java:129)
        at java.io.BufferedInputStream.fill(BufferedInputStream.java:183)
        at java.io.BufferedInputStream.read(BufferedInputStream.java:201)
        - locked <0xe7bf4cf0> (a java.io.BufferedInputStream)

        - locked <0xe7bf2c10> (a org.postgresql.core.PGStream)

org.postgresql.jdbc1.AbstractJdbc1Statement.executeUpdate(AbstractJdbc1Statement.java:273)
        at
org.postgresql.jdbc1.AbstractJdbc1Statement.executeUpdate(AbstractJdbc1Statement.java:259)

Does that mean the postgresql server failed to send the result of the
update ?
Any idea on how to prevent this ?

Any help would be appreciated,
