Hi there, I'm running 6.8.

 

I noticed all the live updating to the Dashboard webpage stopped working (no disk utilization bars updating, stuff like that) and under the Memory section the log bar was red+full. Here's are the types of messages in the logs:

I did a few searches and found sometimes the wrong web browser can cause this. I'm using Brave  Version 1.1.20 Chromium: 79.0.3945.74 (Official Build) (64-bit). I tried completely rebooting the client machine to see if the errors cleaned up. I'm going to leave the browser down overnight and see if any sort of self-healing occurs.

 

I'm attempting to use the gui to generate a diagnostics zip. It's been running for about 5 hours. If I can't get it to complete, what's the most useful information I can hand pull from the command line? Syslogs have seized up at size 70MB of error messages similar to the above with a final message that only partially got written to disk. Haven't had anything new in syslog since 12:31 am this morning. I can hand-execute the diagnostics steps and post something, just let me know if what may be useful. In the meantime, I've attached a snapshot of the memory section on the Dashboard.

 

Thank you for any help you can offer.

Syslogs attached. They compressed quite nicely.

I have the same issue. Have you been able to fix this?

I'm running into the same issue. Any ideas on what's going on? 

Same issue here.

Same Issue here.  

Following.

 

However, did this and it seems to have fixed it.  Will keep an eye on the log and see if the errors come back on.

/etc/rc.d/rc.nginx restart

I have the exact same problem. restarting the service does seem to fix the issue for now. I will keep tabs on it as well

Please try FireFox or actual Chrome and see if issue persists.  This might give us a starting point.

Anything come out of this ?  I have the max red bar on memory for the log and just keep getting this in the log ...

On the dashboard the memory for the log is 100% full.

Mine just happened again today...  @limetech, any thoughts on this?  It seems like there are several of us that have this issue?

I am also having this exact same problem

What Unraid OS release?  Please update to 6.9 if not already on 6.9

I'm on 6.8.3 ...  Which I thought was the latest stable??  Are you saying we should try the latest beta?

Yes, though it is "-rc" now.

I was just having an issue with what I thought was my USB stick, and after a long day of re-establishing my Unraid server on a new USB stick, I still seem to have issues. A little bit more digging and come to find out, I have a log at 100% and it is getting blasted with:

So you are telling us to update to an RC version of Unraid and this issue will magically go away? Why did this just randomly start happening? I have been on 6.8.3 since it was released and just now I am having these issues? Something isn't adding up. Can you please explain further?

Same Issue here.  

Following.

 

However, did this and it seems to have fixed it.  Will keep an eye on the log and see if the errors come back on.

/etc/rc.d/rc.nginx restart

Doing this temporarily fixes the issue, I'm much more interested in a permanent fix...

Same issue here... Still on 6.8.3 and don't want to upgrade to an -rc branch as I don't have enough time to provide feedback on it.

/etc/rc.d/rc.nginx restart temporarily solved it, but we'll see for how long.

I'm having this problem too!
