Like the title says. I've done MemTest for 20'ish hours and RAM tested fine. I'm running on an HP290 G1 (i3 9100) w/ 16gb ram. HBA card and 9 drives.

I've worked with some people on the discount to clean up some share configs, but thought I would post here. logs and diagnostics are attached.

When the problem starts all docker webui goes down. No unifi, no Nextcloud, heimdal, nothing. Server responds to pings, but no ssh.unraid logs.txthomeserver-diagnostics-20250731-1734.zip

In my experience, these errors can be the result of the server being close to exhausting the memory, GUI can become extremely slow, like 1 minute to open the dashboard, try limiting the memory for VMs/docker services, or adding a little more RAM.

It could also be one or more containers hogging the CPU, try pinning only some cores to them, and leave cores 0/1 available for Unraid.

Also, recommend trying a couple of other things, go to Settings - Global share settings and set the Number of fuse File Descriptors to the max, and enable this:

thanks. I'll look into pinning VMs and Docker to cores 1,2,3 and leave unraid core 0. I've also updated the global share settings fuse flags to max and enable flash drive activity fix.

I've also reviewed Nextcloud, which has had a LOT of new features and I really just use it for cloud storage for clients to drop off files for me (and for me to share back). I went through all the settings and disabled a LOT of the extra stuff that I am not using. So hopefully that helps as well.

I'll check back in a few days!

Might of found the issue. Scrypted - used to turn non-home kit cameras into home kit cameras. Apparently if you have had it installed for a while there was a plug in called "python codec", which has been causing issues lately with memory leaks. I just happen to check my Glances dashboard and Scrypted was using 7GB of memory and the system was at 90% of ram used. Restarted Scrypted and memory went back to about 1.2gb.

Deleted the plug-in and now memory is at about 800mb. Will continue to monitor.
