CLOSE_WAIT

[davez]

Hi, running netstat -a on my solaris 9 box reveals an abromally high number of close_wait connections on the system related to an application. Is it possible to remove these without performing a reboot?

Cheers

Look at this link Davez... It's pretty long... Search for CLOSE_WAIT.

They'll time out.

In certain cases the process that opened the connection will no longer exist... The following procedure may allow you to terminate the hung tcp connection ....

Example configuration :

Local IP = 10.10.4.8 Hex= 0x0a0a0408
Local Port = 8002 Hex= 0x1f42

Remote IP= 10.10.140.47 Hex= 0x0a0a8c2f
Remote Port = 1319 Hex= 0x0527

Command :

ndd –set /dev/tcp tcp_discon_by_addr
“0a0a04081f42 0a0a8c2f0527”
