websites to new server and I using same settings like on old server but
now

nginx version: nginx/1.8.0

As per logs, someone or something send SIGTERM to all nginx
processes, including master (pid 100690) and all workers (100691,
100692). Check your server to find out how this happened.
Usually such things happen due to bugs in log rotation scripts or
something similar.

Hello,

It can also be oomkiller killing nginx due to low resources, you should
monitor & check the other logs.

2015-12-04 16:43 GMT+02:00 Maxim D. [email protected]:

egrep -i -r ‘killed process’ /var/log/

result nothing…
