[Sophos UTM 9.000] High memory/swap usage

Hello,

See the screenshot below for a monthly view of our Sophos UTM memory usage.
I think that the swap and memory usage is verry high. After a reboot it is normal for a few days but grows up fast.
Is this a problem? We have 3.3gb memory.
CPU is normal around 15%

We have the following services enabled:
- Firewall
- Intrusion Prevention
- Web filtering
- Network visib.
- FTP & SMTP proxy
- Antivirus, antispam & antispyware

Hi, the % memory using isn't very meaningful as any OS will do a lot of caching.

If you can login on the console, and run 'free', it will show you something like this:

loginuser@fw:/home/login > free
             total       used       free     shared    buffers     cached
Mem:       2073360    1851536     221824          0     404664     576984
-/+ buffers/cache:     869888    1203472
Swap:      1048572        704    1047868
loginuser@fw:/home/login >

The numbers in bold are the total used RAM, less cache/buffers, and the total used swap.

This is from my home system running 9.003, and ~900MB used is typical for my system.

I only am running IPS and Application Detection.

Here is the result of free.
