Signal 9 is SIGKILL sent to the nginx worker process.  Killing 
nginx worker processes will obviously result in various problems 
with caches, no surprise here.

You have to investigate further who and why sent it, and eliminate 
these conditions.  Most likely it was something like OOM Killer 
(check system logs), though may be something different.

Note that in nginx 1.13.0+ the log message in question will 
contain PID of the process which sent the signal.  If you won't be 
able to find out the source of the signal, upgrading to nginx 
1.13.x might help with the investigation.
