Hello all, long time user, first time poster. We've been running FreeNAS on a production system successfully for many years We're currently running 11.1 and upgraded late last year. In the last couple of week's the GUI performance has tanked. I can log in and get the main page but some tabs time out completely or are terribly slow. For example I clicked on the 'Control Services' button about 10 minutes ago and its still trying to load. I've tried Chrome, Edge and IE with similar results. The CLI seems to work normally and the processor is bored. I tried restarting the Django and Nginx services but the result is the same. Our CIFS share seems to work fine and the VM's hosted through iSCSI also seem to be unaffected. Assuming the GUI is updating, I have the green 'Ok' light. I plan to do a full reboot at the next maintenance window but thought I would post here in case others have a better idea.

Here are some log outputs to help start off.

How much swap is in use?

Have a look at the reporting tabs (if you can), specifically the memory ones

It's odd you have 30G of Wired memory, but only ~4.2G of ARC. What is the other 25G doing? I agree with @Stux, you need to find out what is sucking up all that memory.

I believe 11.1 had a memory leak (apparently fixed in 11.1-U1), but I would have expected a much higher percentave of Inactive memory were that the case. But maybe not.

I did manage to get the reporting pages to load. I'm not sure what to make of it though. It seems to have plenty of free swap.

Yea, you can't conclude much from that reporting graph. Assuming you still have less than 5GB of ZFS ARC, then something is taking up all that wired memory. I think you can get an idea if you run the following from a command line, which should give you the processes using the most memory:
Code:
# top -n -o res


BTW, on the swapping, while it's probably not bad, several folks have noticed some excessive swapping in lightly loaded systems. Separate issue, but you can read about it here: https://forums.freenas.org/index.php?threads/swap-with-9-10.42749/page-5

The title says 9.10 in the title, but we've seen it in 11.0 and 11.1 as well. Essentially you can play with these values to "correct" the issue. The values that work for the "free_target" values will be system dependent.
Code:
vm.v_free_target: 32768
vfs.zfs.arc_free_target: 32768

Thank you. So we were able to reboot the system today and its super snappy again. I took the opportunity to apply the most recent 11.1 updates (11.1-U4) in case it was that memory leak issue. I'll try to read up on how you adjust the ARC, I always thought it managed itself. Here are the stats again but obviously this is following the reboot.

Seems like the ARC is using it now, must take time after a reboot to decide what it wants.

Yes, the ARC does adjust itself dynamically. However it can be tuned a bit. For example one can set a max (and min) value ("do not grow larger than this value, ever"). The parameters I showed above steer the dynamic operation of the arc by telling the system how much free memory to keep around (in my example "keep 32768 pages of free memory around, even if you have to adjust down below arc_max to do so"). And there are others. I wouldn't recommend playing with it too much.

I still think your issue is something taking up a bunch of memory that then limits the ARC size. You'll need to discover that those processes are should the issue continue. After you've been running a while it will be interesting to see the output of that top command again IF the ARC continues to be limited to under 6GB of memory.

You an also look at the output from the following to show you what is happening with the ARC: # arc_summary.py | more
