I'm having some serious ongoing problems with nginx, I'm on 6.8.3. The log was filling up, mainly with nginx errors, eg:

May 10 05:30:02 tobor-server kernel: Code: Bad RIP value.
May 10 05:30:02 tobor-server nginx: 2020/05/10 05:30:02 [alert] 7919#7919: worker process 21090 exited on signal 11

May 10 05:30:02 tobor-server nginx: 2020/05/10 05:30:02 [error] 21187#21187: nchan: Out of shared memory while allocating channel /disks. Increase nchan_max_reserved_memory.
May 10 05:30:02 tobor-server nginx: 2020/05/10 05:30:02 [error] 21187#21187: *1848775 nchan: error publishing message (HTTP status code 507), client: unix:, server: , request: "POST /pub/disks?buffer_length=1 HTTP/1.1", host: "localhost"

I needed to generate the diagnostics using the terminal as the UI is not responsive for certain pages.

I'm planning on doing a memtest when I'm near my server next, any other ideas I should be looking at?

Just did a reboot and get this within 5 mins:

May 11 17:47:11 tobor-server nginx: 2020/05/11 17:47:11 [error] 8916#8916: *2941 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 127.0.0.1, server: , request: "GET /admin/api.php?version HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "127.0.0.1"
May 11 17:47:11 tobor-server nginx: 2020/05/11 17:47:11 [error] 8916#8916: *2943 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: ::1, server: , request: "GET /admin/api.php?version HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "localhost"

Different errors, but related to nginx & php?

 

EDIT: Ok ignore those errors, they're related to netdata as per this post:

Any ideas about the initial problems?
