Memory swap usage 9.1GA and UTM220

Simon Shaw
We have a UTM220 device, upgraded to 9.1 yesterday.

40 devices/users protected.
Network Visibility, POP3 Proxy, RED, Endpoint Protection, WAF and HA are all OFF.
HTTP Proxy web caching is off.
IPS is using only 7980 of 15806 patterns.

75-300 users are recommended by Sophos for this unit type.

However memory swap climbed almost instantly to over 50% of RAM.  I know there has been some discussion on swap usage, but am unsure of the outcome.  CPU looks fine.

Can someone send me a summary of Sophos comments on swap/memory usage as I'd really not like to throw 100-200 users on this device...

    Interesting, Simon.  I have all of my clients on single-scan with Avira.  If you guys set up the same way, does the swap problem disappear?

    I wouldn't be surprised to learn that the newly-ported Sophos AV hasn't yet learned to play nicely with the Astaro virtual memory manager.  If you guys think this might be an issue, please submit a Support ticket to Sophos to report the bug.

    Cheers - Bob
