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.

SYNOPSIS

       String microRecv( NetHandle h, Int maxlen=-1, Int microtimeout=0 )

ARGUMENTS

       h The connection

       maxlen The maximum number of bytes to read (or unlimited, if negative). For TLS connections, this is always unlimited.

       timeout	The  number  of  microseconds to wait without input before timing out. The default is zero. For TLS connections, this parameter is
