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.

MEMCACHE.CONNECT(3)							 1						       MEMCACHE.CONNECT(3)

Memcache::connect - Open memcached server connection

SYNOPSIS
bool Memcache::connect (string $host, [int $port], [int $timeout]) DESCRIPTION
Memcache.connect(3) establishes a connection to the memcached server. The connection, which was opened using Memcache.connect(3) will be automatically closed at the end of script execution. Also you can close it with Memcache.close(3). Also you can use memcache_connect(3) function. PARAMETERS
o $host - Point to the host where memcached is listening for connections. This parameter may also specify other transports like unix:///path/to/memcached.sock to use UNIX domain sockets, in this case $port must also be set to 0. o $port - Point to the port where memcached is listening for connections. Set this parameter to 0 when using UNIX domain sockets. Please note: $port defaults to memcache.default_port if not specified. For this reason it is wise to specify the port explicitly in this method call. o $timeout - Value in seconds which will be used for connecting to the daemon. Think twice before changing the default value of 1 second - you can lose all the advantages of caching if your connection is too slow. NOTES
Warning When the $port is unspecified, this method defaults to the value set of the PHP ini directive memcache.default_port If this value was changed elsewhere in your application it might lead to unexpected results: for this reason it is wise to always specify the port explicitly in this method call. RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 Memcache.connect(3) example <?php /* procedural API */ $memcache_obj = memcache_connect('memcache_host', 11211); /* OO API */ $memcache = new Memcache; $memcache->connect('memcache_host', 11211); ?> SEE ALSO
Memcache.pconnect(3), Memcache.close(3). PHP Documentation Group MEMCACHE.CONNECT(3)
