Did the RAM limits change for Home edition for 16.05.2 to 4GB?

Just to put it out there ...

This has all the symptoms of a licensing issue.

Given that the problem remains after rolling back to MR-1.  It doesn't appear to be in the OS.  It smells like the licenses were modified, 'downgraded', upon applying the MR-2 update.

Here is my outputs:

Sophos Firmware Version SFOS 16.05.2 MR-2

Hi BrianHawkins1,
No idea if it is releated but I have a ZBOX CI323 NANO-U and it uses an Intel N3150 cpu as well. What hardware are you using for your XG? DavidWilliams1 what hardware are you running sophos on? I agree with DavidWilliams1 and think this is some kind of weird licensing issue, but maybe its a licensing issue with ties to a certain piece of hardware?

the kernel RAM limits appear to be correct... something else is restricting the RAM.

Interesting!

I use the same ZBOX setup, with an Crucial 8GB Kit and a 60gb SSD.

BOOT_IMAGE=16_05_2160 quiet maxcpus=4 mem=6G ZD=80 SM=0 ro console=tty0 console=ttyS0,38400n8 console=ttyS0,9600n8

I recently setup Home edition on a zbox Ci323 nano as well. It has 2x4G memory sticks, They were fully tested using memtest86 before installing XG.

I booted the system from a linux cd after seeing only 4G used by XG and the linux OS sees all 8GB.

Interesting.  I too am using a ZBOX CI323 NANO-U.  I have 2x 4GB sticks. 

Since I am at work I can not get the console information, but will run that this evening.

My test so far.

Have the memory test to do.

UPDATE - My memory test (PASS 1)

sachingurung said:

Finally, a memory test. Refer: https://community.sophos.com/kb/en-us/125025. Note: It may take 1-2 hour time to complete a full scan of 6 GB. Post the output.

Ok, is this really necessary?  This test the physical memory by running a test pattern.  I feel pretty comfortable saying that everybody's memory didn't go bad at exactly the same time.
