Hi so I have lots of clients on long lived tcp connections , getting rp into 2 back end app servers
I had a line in my error log, saying one of the upstream was failed caused it timeout - then I got this 2017/05/18 13:30:42 [notice] 2662#2662: exiting 2017/05/18 13:30:42 [notice] 2662#2662: exit 2017/05/18 13:30:42 [notice] 2661#2661: signal 17 (SIGCHLD) received 2017/05/18 13:30:42 [notice] 2661#2661: worker process 2662 exited with code 0 2017/05/18 13:30:42 [notice] 2661#2661: signal 29 (SIGIO) received I am not sure what initiated this ? there are no cron jobs running at that time and it looks like a lot of my long lived tcp session where TCP-FIN'ed. I also checked my audit logs to see what command / process run at that time ... nothing that signaled or initiated a nginx reload ... Alex
