Oh, I didn't notice that file. :-)
Recreating is just booting and waiting for a week, but the box is still up.

This is the line that stands out (complete file attached, 137 lines).

tcp6_sock 111663 111664 960 4 1 : tunables 54 27 0 :
slabdata 27916 27916 0

I seem to remember a changelog mentioning a leak being fixed in ipv6 code,
but it looks like there may be another one? The only ipv6 service running is
sshd, and the mrtg-sshs that go off every 5 minutes are NOT over ipv6.
netstat -na shows nothing interesting. Only the ssh I connect with uses a bit
of ipv6 (ffff:1.2.3.4). So, one listening socket, and one established.

$ cat /proc/net/sockstat6
TCP6: inuse 2
UDP6: inuse 0
RAW6: inuse 0
FRAG6: inuse 0 memory 0

$ cat /proc/net/rt6_stats
0000 0006 0000 0008 0000 0008 0003

nothing over 6 in /proc/net/dev_snmp6/*

$ cat /proc/net/snmp6
Ip6InReceives 223315
... just 0 ...
Ip6InDelivers 223312
... just 0 ...
Ip6OutRequests 223312
.. nothing that looks interesting ...
