Why are there multiples of these processes

MarioG

I recently converted from 2.4.4 to 2.6.0 via fresh install using previous config at install time. While looking into why memory increased to much I found multiples of some processes and ask if any reason for these to be multiple:

php-fpm: pool nginx (php-fpm)
This goes from 3 to 7 averaging processes, each process uses the largest amount of memory. ps aux shows 135112 +- each. This affects memory more than anything. Unfortunately, I had 2 power outages that backup power ran out and had to restart, so I don't know if the number of processes goes down or just keeps going up, will need to wait longer.

nginx: worker process (nginx)
Always shows 2 of these.

/bin/sh /usr/local/sbin/sshguard -i /var/run/sshguard.pid
Always shows 2 of these.

After more data collection, I will be posting memory questions separately. Thank you.

That's using ps -aux at the command line directly?

@stephenw10 Forgot to mention that. It was the web GUI because the machine does not have a display or keyboard. I found out top does not work in the GUI command line.

Diag > System Activity shows the output of top -aSH

@stephenw10 Thanks for that! Yes I see a lot more info/lines, but it does not answer my question of if those duplicates are normal or not. The top command will not convert to excel cleanly like the ps aux command so I can sort how I want. I don't want to address the memory issue until I have more info. Do you know if the duplicate php-fpm: pool nginx (php-fpm) tasks are normal? I also notice in top there are 17" /usr/local/libexec/ipsec/charon --use-s" lines 58M each! and many more with multiple instances. Just trying to get a hold of some basics so I can ask about the daily memory growth.

Duplicate php processes are normal, yes:

@stephenw10 thank you very much! I am working on why my memory utilization went from 3-4 percent to 11-12 percent and growing. Once I collect and compare the top info for a few days I will seek more help. Thanks for the quick responses.
