> Hi,
> Below is the complete description of the issue,
>  * Running a java application which creates a good number of connections with derby on
the machine X.
>  * We are running the derby database server on the machine lets say Y.
>  * We explicitly block the listening of 1527 port of system X traffics on system Y in
the network until it thrown connection exception and then again established the network between
the two systems.
>  * After the java application has finished execution we found there are still some connections
remained open in derby.
>  *  We can see open connections in derby although we have terminated the java application.
>  * We have restarted derby to free up these connection.
>  * Concern here is, how these connection are generated, is these connections are broken
/stale connection made during the network reset, if YES then, how to these connection will
be auto deleted or handled in derby ?
>  * Derby version used
