Kamailio websocket state is going into FINWAIT1 without sending FIN message out when we do service kamailio restart. 

I have a Primary and Secondary node configured. When I perform switchover socket status is going into FINWAIT1 state without sending FIN to the client hence client  status is showing established, This is happening 90+% of times but does work sometimes.

AT Kamailio:

[root@localhost ~]# netstat -tunelap | grep 41034

tcp        0      1 172.27.45.198:9040      172.27.6.98:41034       FIN_WAIT1   0          0          -

[root@localhost ~]#

 

AT Nginx (client):

root@meet:~# netstat -tunelap | grep 9040

tcp        0      0 172.27.6.98:41034       172.27.45.198:9040      ESTABLISHED 33         763106     1322/nginx: worker
