Howdy,
We are running zones on a number of Solaris 10 update 3 hosts, and we
are bumping into an issue where the kernel doesn't clean up
connections after an application exits. When this issue occurs, the
netstat utility doesn't show anything listening on the port the
application uses (8080 in the example below), but connections are
still listed in the ESTABLISHED state:
$ netstat -an | grep LISTEN
*.22 *.* 0 0 49152 0 LISTEN
127.0.0.1.25 *.* 0 0 49152 0 LISTEN
127.0.0.1.587 *.* 0 0 49152 0 LISTEN
$ netstat -an | grep ESTAB | grep 8080
10.32.51.230.8080 10.10.12.6.34252 65535 0 49248 0 ESTABLISHED
10.32.51.230.8080 10.10.12.7.54136 1 0 49680 0
ESTABLISHED
10.32.51.230.8080 10.10.12.8.19335 62975 0 49248 0 ESTABLISHED
< .... >
Normally I would open a ticket with Sun when I bump into issues with
Solaris 10, but I couldn't find anything in the bug database to
indicate this was a known problem. Does anyone happen to know if this
is a known issue? I rebooted the server with the '-d' option the last
time this issue occurred, so I have a core file available if anyone is
interested in investigating the issue (assuming this is an unknown
problem).
Thanks for any insight,
- Ryan
