Wire memory slowly increasing
-
Thanks Kom, that is very useful info on squid.
That command didn't seem to give me anything helpful. Below is what it returned. I used the IP of the LAN interface of the pfsense box.
In any case, I saw one of the recommendation in that link was to lower the cache_mem aka memory cache size. I had it set to 1024 MB since I have a lot of memory. Maybe I was too ambitious with that so I lowered it back to the default 64 MB. I also lowered the Maximum object size in RAM back to the default 256 kB. I had that set to 1024 kB. I also cleared the local cache, but it hasn't made any impact on memory usage, at least not any immediate impact. If anything, wire memory went up a tad. I guess I'll keep an eye on it. Maybe it needs a reboot?

This is a common error.
You need to go to Services - Squid proxy server - Local Cache - Squid Cache General Settings - External Cache Managers.
Set it to the LAN IP squid listens on as well as 127.0.0.1 like this:
10.10.4.1;127.0.0.1
Replace 10.10.4.1 with your LAN IP. Save it and then try the squidclient command again.

Awesome! That did the trick. This looks more useful, but I don't know what it really means. The section on analyzing the cache manager output doesn't seem to apply to the version I'm using. Here is the new output. I think the total memory accounted for looks low. Only 11 MB.

"Wired memory" is a BSD specific term for kernel memory that is "wired in place" and can't be swapped out by the memory management. What you're seeing might be normal depending on the circumstances, unless your system runs out of memory and starts swapping heavily there might be no problem to fix.
-
Squid only appears to be using ~256 MB.
-
Oh, based on your top(1) output you are using ZFS and the ARC cache of ZFS is using 3465 MBs of wired memory. Looks totally normal to me. ARC cache is auto tuned/scaled based on the available memory so you don't really have to worry about it. The rest of the wired memory is used by other kernel data structures that can't be swapped out.
-
Thanks kps, nothing to worry about is what I want to hear. I'll keep an eye on it.
Thanks Kom, I think squid may not be an issue then. The changes I made to squid didn't affect the memory use, so that kind of hinted at that too. I'm hoping it's nothing to worry about. I'll worry when swap starts being used. Thanks for the info on squid anyway. I'm glad I learned something new today.
-
If it ever becomes a problem there's a system tunable that you can set to limit the amount of memory allocated for the ARC cache. Place this in /boot/loader.conf.local (assuming you want the limit to be at 2048 MBs).
vfs.zfs.arc_max=2048M -
Great! Thanks. I'll keep that in mind if it does become a problem.

Guess what... swap is now being used!!! I was fearing this and now I'll have nightmares. Users on the network as well as myself have been noticing a "slow connection". This could explain it. Why is my swap being used though? My memory according to the Dashboard is 90% used.
According to the last datapoint in the memory graph, it's nowhere near 90% ???
According to the system activity, memory usage is not that high either... I think.
And according to ps -aux, the memory usage is not that high either.

Help!

@kpa Would this ARC cache be the reason my memory usage is high but it's not being reported by pfSense anywhere other than the Dashboard? I'm afraid to change anything without knowing what exactly it's doing or not doing.
Thanks,
Raffi -
I made the change for the zfs arc cache in loader.conf and then rebooted. The memory is back down to normal and no swap usage as expected. Hopefully that will solve it for good. I'll keep an eye on it.
