How would I troubleshoot memory related slowness / possible memory leak?

[ifican]

Nutshell running 12.2.1 i didnt see uptime but last week or so network was spotty with slowness. Today got so bad i could not effectively work. After take literally about 5 minutes to get gui to load and log me in, i noticed ram utilization at 6.5g (8 installed). This number normally sits around 2g used, after a reboot things are back to speedy as usual and ram is sitting at just under 2 as expected.

My ask is what steps can one take to monitor and or troubleshoot this to determine what the cause is?

I have poke through the forums, found things on virus lite and others but nothing specific to mem leaks or troubleshooting this behavior.

ps aux --sort rss

usually but not always narrows it to a single process.
from there you just have to further investigate that process.
if its java, you can take a heapdump or check the proc smaps or proc map

This is just an update,,,,, i didnt get a chance to run above command as i had to reboot to bring a meeting back alive. Same general thing though, i did see uptime was 79 days. Since i am now on fresh reboot plan now is to try and monitor what process is eating up memory and potentially leading to the above condition.
