RE: System running out of ports

This is what I have done, however I need to fix the problem. I don't think
this system is up to date on PTFs, but I wonder what has happened to have
this start to happen.
Thanks to all those who have responded.

This has nothing to do with reclaim storage as this it IP ports not storage.
using netstat *cnn you can take option 4 next to the connections that have
been dead for more than 2 minutes. this will free up ports for your use.

Prompt the CHGTCPA command. Check the 'TCP time-wait timeout' value. I
suspect that it's set too high.

The situation is quite weird, because when in 'time-wait' state, the sockets
are really just waiting for a period of time as a "just in case"

type of measure. It shouldn't involve anything other than waiting for

the timeout value.

So unless that timeout value is too high, all I can think of is a problem in
the OS (maybe some corruption somewhere?) If it's not the timeout value,
and an IPL and/or RCLSTG doesn't help, I'd call IBM.

I have a customer with a 170 that has been running and running for

We rarely touch it.

In the past 2 weeks I have received a few calls about printers that
have stopped working. In looking at the spool job's joblog, I can see

message that the system has run out of port for LPD/LPR printing.
Further inspection of the NETSTAT (option 3) screen indicates that
there are literally thousands of jobs initiated from the iSeries to
the printer in a TIMED-WAIT status, with idle times measured in days.

In looking at other iSeries boxes, it appears that for every spool
file send from the iSeries to a printer, the iSeries opens a new
connection with a local port to port 515 on the printer, sends the
data, goes idle, and after about 60-90 seconds, the connection

disappears.

So, what is my customer with the 170's connections not ending

gracefully????

BTW, the client is at V5R1.
