Hi guys, I got an error from Fix Common Problems app saying:

I have checked the sys log and got:

I have read somewhere on this forum that it may be because of the mover out of memory but i dont think this is the case because I have all vm's and dockers turned off and have about 48 Gb of ram, I find it hard that the unraid system would use all 48 Gb.

 

 

 

"Tainted" in the linux world doesn't mean what you would in the "English" world think it does.  

 

Page Allocation Stalls:  Basically, the server is having a brain fart trying to allocate memory to such and such process.  Basically harmless (but the app in question will pause while the OS sorts it all out).

 

Installing the tips & tweaks plugin and then this might help:

 

 

Thank you Squid
