Hi All,

We have an application (sap webdispatcher) which is listening on a particular port, at a certain (busy) time of the day the port/application stops responding on the port id.

The cpu/memory/disk all checks out fine, no errpt errors or vio server errors

The application displays an error, being investigated by vendor

Without any outside interference the port/app will start to respond on the port again.

Can anybody advise how I can get more info on the port usage, i.e. are buffers/cache being exhausted etc

I can't find commands that drill down to the particular port ID

Any ideas

Thanks

Use netstat...

netstat -an       shows port activity. look at the number of remote connections for the service and the state of the connections (send and receive queues); look at

netstat -M         shows network memorys mbufs stats

netstat -ano     displays detailded data about a socket

see man pages for nestat
