I'm still trying to troubleshoot my parity drives becoming disabled.  I bought a new controller card, installed it, and started another check last night.  When I got up this morning to check on it's progress, none of the drives are showing any issues (yet).  However, when I checked the system log, it has a LOT of errors about being out of memory.  I'm not sure what could be causing it.  I have 128GB of RAM, and it's rarely over 10% used.  Is there something else going on I should look at?

 

Current System Log:

nchan: Out of shared memory

Nchan is running out of RAM, not the server, updating to v6.12 may help.

What is nchan?  If it's not something critical, I'll wait until the official release is available.

Do you open webgui on an android device i have an issue if i change to a a different tab the nchan process stores messages as cannot deliver to client

I have a Samsung Tablet (yes, android) that I use as a remote client.  I do Remote Desktop via an app with it to connect to various VM's and my main PC.  I also use the Chrome browser to directly access the server occasionally.  Now that you mention it, I do recall reading something about that being a problem... using andoid browser to access unraid.  Is there a way to fix that?

Only solution I know off is to close the tab on the browser with unraid gui. Also in later relase nchan processes are stopped if you log out of the gui.

Yeah I definitely have a tendency to leave the tab and/or browser open when I'm not using it.  So with the new release I would still have to log out if I'm not using it?  Probably easier to just remember to close the browser.

Yes
