I'm not sure how long it's been building up, but there are more than 4000 "Closed" TCP connections on a web accessible Plan 9 server, according to netstat. Is there a simple way to clean up and delete all these entries or does one have to do something dramatic? I can't drop the network, the server is a long way from here :-)
I don't like rebooting, but I don't like 4000-odd netstat entries either. Hm, many are local "ticket" connections, you'd think they'd go away once dealt with. The kernel is a little less than two years old, I'll have to consider an upgrade. ++L
