Hello,

As you said before killing nginx worker is connected with third party module which is Linux kernel Out Of Memory killer.

Because nginx is using too much memory OOM killer score is about 800-900 point where 1000 is maximum, which is why kernel is killing out nginx worker, and after that files in tmp catalog are not deleted and disc is full.

About configuration, we are storing 40GB cache because size of files which are stored is about 700MB to 1GB and stored for 1d. Our machines have 24GB and at some time nginx uses 22GB-23GB, and after that OOM killer start and kill our worker.

My question is why nginx is using so much RAM, and how to prevent nginx from using so much RAM. Or other possibilities to stop killing nginx worker.

Best Regards,
Grzegorz Ćwikliński
