Topic: Memory Problems with SME 5.6 ?

[James Shields]

I use phpSysInfo 2.1 to keep an eye on a couple of servers that I look after. I notice that since upgrading to SME 5.6 that these servers are always showing over 90% on memory usage, irrespective of the amount of RAM.

Is this a glitch with the way 5.6 handles memory, or is phpSysInfo reporting incorrect information ?

Examples of this can be seen on the 2 servers in question.

I use sysstat-4.0.5-3.i386.rpm which gives the same results.
Memory used, buffers and cache all slowly (takes more than a day) reach saturation.
I did not use this before the upgrade so I can't confirm that this is something new.
Perhaps it is by design.

BTW did you deliberately open your statistics for us to see or is it always visible from the outside without encryption and pasword?

You didn't buy your RAM to sit there idle did you? The operating system is using the RAM that you provided to it. This is a Good Thing. (The linux FAQ will tell you this).

I observed the same thing and resintalled PhpSysInfo v.2.0, which reported the exact opposite amount of free memory vs. memory in use.

I checked it with a Linux prompt and it turns out that 2.1 is correct and 2.0 is the one showing the incorrect information.

I could find any mention of it in the changes log to PhpSysInfo though.

The default configuration of SME means memory is being allocated for the services that tend to get the most use. eg. Squid.

As Charlie mentioned, this is a good thing.
