Is it normal for plex to use 100% of 8GB RAM?
Config:
LXC
Ubuntu 16.04
Plex: Version 3.37.2
Don’t know enough yet. Please explain further.
Currently there is 2 active streams one is direct play the other is converting, the container is using 100% RAM. I just took a look with top and only 500Mb is being used the other 7.5Gb is all cached data. I did not notice this when i was on ubuntu 14 only happened since switching to 16.
If PMS is using 100% of container RAM then increase it.
By your initial question, it sounded like PMS was using 100% of the system RAM.
Increased the container ram from 8GB to 16GB. The container isn’t using more RAM than it has allocated to it.
If you are showing 500mb in use and 7.5gb cached, it sounds like things are working like they should. Having 7.5gb free memory and not using it for caching would be wasteful to the system. What am I missing? Your plex container should probably be ok with 2-4gb ram.
I just thought it was odd since it didn’t do this on Ubuntu 14.04 with the same version of plex.
I would think it odd that it did not do that. It has nothing to do with Plex and more do to with the kernel. That is the way most current OS works. Cached memory will be released as soon as it is needed by an active process. But when it is not needed, it stores commonly used objects in memory. You will often seen very little memory listed as free in Linux (unless the machine was recently booted or tweaked in some manner),
drinehart is correct. You’re seeing normal Linux behavior. Should you find active use at 7.5 GB of 8.0 GB then there is concern but only 500 MB of 8GB, with the rest being buffers, this is normal.
