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 years.
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.
