Since February, I have my 2 hosts to create in 2017 who have trouble with port 9983. When, I start them all, it’s fine. 24 hours later, the host is inaccessible on port 9983 (even in localhost). Port 9982 is still accessible.
Well obviously siastats.info warned me, when not online.
I thought that I had a problem with CLOSE_WAIT? So I set my network parameters, it is evacuated every minute (normal operation under linux / ubuntu 16.04 LTS extended support).
The problem seems to arise when I reach 2000 connections.
Actually, my host work and I closed the creation of new contract:
Total: 253 (kernel 850)
TCP: 188 (estab 45, closed 7, orphaned 2, synrecv 0, timewait 3/0), ports 0
Transport Total IP IPv6
850 - -
RAW 0 0 0
UDP 11 7 4
TCP 181 18 163
INET 192 25 167
FRAG 0 0 0
root@sial01s01:~# netstat -nap|grep 9983|grep WAIT|wc -l
root@sial01s01:~# netstat -nap|grep 9983|grep -v WAIT|wc -l
I would put the stats as soon as the host will no longer be accessible.
There is a maximum number defined in siac on port 9983 and one idea ?
