Connections not shown in netstat output

I have a TCPIP server application (a Vendor package) which by default allows 10 connections. It provides a parameter to allow us to increase the maximum allowable connections in case it is needed. Intermittently this application is failing with maximum number of connections reached even when there is no client activities. I am the application support and do not have root authority. When the error occour, I use netstat -an to display the connections. But I do not see any connection to the port that the server application is listening on. The server application is listening on port 7780, the command I used was netstat -an | grep 7780. But there no connection showing. I also pipe the output of netstat -an to a file and read through it carefully. I did not see any connection to that port. Is it possible that netstat -a will not show all connections or do I actually need root authority to see all ? If not, then how can I determine what is the problem.

asadmin-create-connector-connection-pool(1AS)			   User Commands		     asadmin-create-connector-connection-pool(1AS)

NAME
asadmin-create-connector-connection-pool, create-connector-connection-pool - adds a connection pool with the specified connection pool name SYNOPSIS
create-connector-connection-pool --user admin_user [--password admin_password] [--host localhost] [--port 4848] [--secure|-s] [--password- file filename] [--terse=false] [--echo=false] [--interactive=true] [--steadypoolsize 8] [--maxpoolsize 32] [--maxwaittime 3000] [--poolre- size 2] [--idletimeout 300] [--failallconnections=false]--raname resource_adapter_name --connectiondefinition connection-definition_name [--property name=value[:name=value]*] pool_name Adds a new connector connection pool. Before you can add a new connector connection pool, you must first deploy the associated RAR file. This command is supported in remote mode only. OPTIONS
--user authorized domain application server administrative username. --password password to administer the domain application server. --host machine name where the domain application server is running. --port port number of the domain application server listening for administration requests. --secure if true, uses SSL/TLS to communicate with the domain application server. --passwordfile file containing the domain application server password. --terse indicates that any output data must be very concise, typically avoiding human-friendly sentences and favoring well- formatted data for consumption by a script. Default is false. --echo setting to true will echo the command line statement on the standard output. Default is false. --interactive if set to true (default), only the required password options are prompted. --steadypoolsize minimum and initial number of connections maintained in the pool (default is 8). --maxpoolsize maximum number of connections that can be created to satisfy client requests (default is 32). --maxwaittime amount of time, in milliseconds, that a caller will have to wait before a connection is created if a connection is not available. If set to 0 the caller is blocked indefinately until a resource is available or an error occurs (default is 60000). --poolresize the number of connections to be removed when idletimeout timer expires. Connections that have idled for longer than the timeout are candidates for removal. When the pool size reaches the steadypoolsize, the connection removal stops. --idletimeout the maximum time that a connection can remain idle in the pool. After this amount of time, the pool can close this connection (default is 300). --failallconnections if true, closes all connections in the pool if a single validation check fails. This parameter is mandatory only if the is-connection-validation-required is set to true. Legal values are: on, off, yes, no, 1, 0, true or false (default is false). --raname module name of the deployed resource adapter. In case of a resource adapter that is embedded in an application, the raname will be appname#raname. --connectiondefinition identifies one of the connection definitions in the deployment descriptor of a resource adapter. Value of connec- tionfactory-interface sub-element in the connection-definition element. --property name/value pair of the configuration properties of the managedconnectionfactory-class of the connectiondefinition for which the pool is being created. The UserName and Password are accepted by default for all pools. The escape character " OPERANDS
pool_name name of the connection pool to be created. Example 1: Using create-connector-connection-pool The JMS resource adapter that is prepackaged with the application server is used for this example. Before you can add a new connector con- nection pool, you must first deploy the associated RAR file. To deploy the RAR file: asadmin> deploy --user admin --password adminadmin jmsra.rar Command deploy executed successfully asadmin> create-connector-connection-pool --user admin1 --password adminadmin1 --steadypoolsize 20 --maxpoolsize 100 --poolresize 2 --maxwait 60000 --raname jmsra --connectiondefinition javax.jms.QueueConnectionFactory --property UserName=guest:Password=guest jms/qConnPool Command create-connector-connection-pool executed successfully EXIT STATUS
0 command executed successfully 1 error in executing the command asadmin-deploy(1AS), asadmin-delete-connector-connection-pool(1AS), asadmin-list-connector-connection-pools(1AS) J2EE 1.4 SDK March 2004 asadmin-create-connector-connection-pool(1AS)
