6.9.4 T43 - RAM issue with plex

[matmar]

Hi,

getting very low ram using plex, transcoding.
only 5% RAM free and 0.5 % swap free.
Anybody has a solution?
Also I do not understand why RAM is not released when I stop using Plex
thanks in advance

It would be better to work with Plex on this case since the Plex process is controlled by them and not the NAS.

I have noticied in a unit recently where Plex's DLNA would take a lot of memory. In a number of cases users do not use DLNA on Plex and can be disabled. ReadyDLNA has a lighter footprint.

You could enabled Secure Diagnostics Mode and PM me the 5-digit number. Please note that I can only tell you what process is taking the memory and if it is related to Plex, then you will need to work with Plex regarding the specific process that is causing the issue.

RAM is used for caching to improve performance and freed up as needed, however on the other hand swapping, such as low % swap free does indicate a problem.

Are you sure that it's Plex that's using the memory?

Which other apps are you running? Which services are you running?

[matmar]

I am using net data NT and squeezbox

For services: SMB, AFP, FTP, readydlna, upnp, http, Https, file search.

For me it is Plex because when I stop and restart Plex it realease immediately plenty of RAM

thanks in advance

Any update? Thanks

Hi matmar,

Have you done any changes on the NAS before the problem started (e.g. add lots of files to library, update Plex, update firmware)? 

Have you also tried contacting Plex and see what they say?

Regards,

[matmar]

Did not do anything particular. Plex told me to ask Netgear....

[mdgm-ntgr]

Can you send in your logs (see the Sending Logs link in my sig)?

FYI I think there was some kind of memory leak fixed in plex recently.

Also if that did not resolve it, are you using any Plex Plugins?

[matmar]

Not solved and I am not using any Plex plugin.
thanks

Hmmm. Not sure what it is then. Are you running the latest 6.9.4 beta?

[matmar]

I have installed RC2, leaks less important but still there
RAM reach 7% free only
Swap 45%
If I switch off then On Plex go back to 75% and 80%

[matmar]

Using EDA 500, maybe it may explain....or not

[matmar]

still leak issue, think to change my NAS, maybe QNAP...

If the leak is in plex, then changing to a different NAS won't help.

I have a huge, I mean h000ge plex library and I have not seen any memory leak or out of memory issues with my readynas or plex.

I do have upgraded memory to 16 gig, so if you are still on stock ram you may consider upgrading. But my ram according to HTOP is stays almost exactly around 3.9G with everything running, and linux uses the rest for cache/buffers.

Out of memory does not necessarily indicate you have a memory leak. It simply means you don't have sufficient ram for the applications that are trying to run.

Thanks a lot, Dlna was the issue
