Clients TCP connections never close

Jeff Kelley
It is 3AM and there is nobody on grid. Netstat shows 260 ESTABLISHED
TCP connections to 8002 and regions ports, belonging to clients that
quit hours ago.

Is this normal?

Is it normal? I'd think not. Is this linux/mono? what version of mono and which kernel?

Could it be possible that something is DDOSing you?
I don't see anything at all like that on any of my linux computers.

$ cat /proc/version
Linux version 3.10.23-xxxx-std-ipv6-64 ([hidden email]) (gcc
version 4.7.2 (Debian 4.7.2-5) ) #1 SMP Tue Mar 18 14:48:24 CET 2014

$ mono -V

$ netstat --inet | grep my.own.ip | wc -l
131

$ netstat --inet | grep 90 | wc -l
230

90xx = regions. Nobody on grid a.t.m.


Also this grid :

$ cat /proc/version
Linux version 2.6.32-431.1.2.0.1.el6.x86_64
([hidden email]) (gcc version 4.4.7 20120313 (Red

$ mono -V

It can't be DDOS since remote addresses are from friends now
sleeping, and myself having left the grid 2 hours ago.
