Hello, I'm trying to figure out what numtcpsock is counting in my container. The number just keeps climbing, but the number of connections stays steady according to the various methods of showing connections (netstat, ss -s, /proc/sockstat)
How can I reconcile the numtcpsock number with what the container reports?
The following shows that I have 507 connections, 114 in time_wait, but numtcpsock says that 1711 socket connections are in use? How do I track down why openvz thinks that there are 1204 more connections than the container knows about?
# cd /proc/net && netstat -nat | wc && netstat -na |grep TIME_WAIT | wc && cat sockstat && cat sockstat6 && grep numtcpsock /proc/user_beancounters && ss -s && uname -a

I'm running proxmox 3.4 using openvz with a Debian 8 template.
Thanks
