Low laods and low memory

[RenDprogrammeur]

On a strange way the memory is going low to 40mb or lower but the server loads stays low on avarage 0.40.

How can this be ?

Even when i restart the server it start at 350mb (got 509mb) within a few hours its down again on 40 mb.

How can this be and how can i fix this ?

When i use top command in putty i see this strange commands.

init
migration/0
migration/1
keventd
ksoftirqd/0
kswapd
kscand
kupdated
bdflush

How can i fix this and what does the commands mean ?

There's nothing to fix. Low free memory means that linux is managing the rest and keeping it ready for use.

Of course you don't have much memory to begin with, by today's standards.

To find out what any of those daemons and/or other programs listed in top do, the best thing would be for you to google them.

Ok, tnx

But i asked my hoster to set in more memory 1000mb extra but it doesnt work.

The bios doenst take the new extra memory how can he fix it that my server will see 1,5gb ?

looks like 512m memory is enough for you by now, you don't need to add more.

And even if it works (meaning even if the BIOS sees it, linux will manage it and you still won't see a lot of available memory.

That's system dependent; only your BIOS manufacturer or system manufacturer can help you.

If you provide the Motherboard manufacturer and model number I might be able to find some information for you.

If the bios isn't recognizing the additional memory we're getting into hardware problems.
It could be because:
1. the memory was not inserted properly, usually the board would not post if this were the case
2. The memory inserted is incompatible with the MB
3. The MB does not support the size of the ram module inserted.
4. The MB does not support the overall size of ram inserted
5. The ram is bad
To mention a few causes.

Sometimes a BIOS flash can fix the problem if it's not with the motherboard design.
