Memory Usage

Magny

Hello Everyone,

Memory usage: 85% of 993 MB

When i go check my PfSense this morning, I saw the memory usage at 85%.What could be the cause for that ? That something I can do for drop this ?

Thanks All,

KOM

That something I can do for drop this ?

Uninstall some packages that are chewing up your memory? My 2.2.4 is at 11% of 2GB, and I have squid, squidGuard, Sarg & Lightsquid running.

Showing me a list of system processes isn't that helpful.

Which version of pfSense, and i386 or x64?
What packages, if any, do you have installed? (System - Packages - Installed Packages)
If you reboot the unit, does it come back up at 85% or does it crawl upwards over time?
What does Status - RRD Graphs - System - Memory show? Is the memory usage flat or does it climb over time?

Magny

Version : x64
Package Install : pfBlocker - squid3-dev - squidGuard-devel
When i restart the same thing happen.

Yeah, either remove the Squid* stuff or get some decent RAM.

426M   417M kqread  1 121:16  0.00% (squid-1) -f /usr/pbi/squid-i386/etc/squid/
```  <- squid proxy is using 417 mbyte allready

Thanks Guys,

i will remove it and i will check if it will drop my memory usage.

By default, squid only uses 8MB or something. And like I said earlier, I'm running squid3 and squidGuard, and only using 11% of 2GB. Magny, what do you have for Services - Proxy Server - Local Cache - Squid Memory Cache Settings - Memory cache size?

Magny

Memory cache size
8

This is the amount of physical RAM (in megabytes) to be used for negative cache and in-transit objects. This value should not exceed more than 50% of the installed RAM. The minimum value is 1MB.
Maximum object size in RAM
32

Yes, I know but users usually tune this particular option so it's what I check first. It still shouldn't be a problem if he has used the default 16x256 cache structure.
