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...

    OK, I thought that the swap-growth issue had been fixed in 9.006-5, but it hasn't, only mostly, not completely.  Sophos, until this issue is fixed, appliances need to have a minimum of 4GB of RAM.

    I agree that 2GB is the right amount if swap works correctly, but there is an issue with every one of my customers on V9.006-5.  Even the one with a 7GB software install grew gradually from 0.00 to 0.32 over a 4-day period.

    Cheers - Bob
