I'm not exactly a Linux novice, but, I must admit that I am novice enough to be unfamiliar with these log entries. I have a few VMs and I've not seen this before on any of them.

I do have the Logwatch level cranked to 10, so this could be normal and I just don't know it.

This machine just runs a general LAMP stack (built using a StackScript).

Any insight into what these entries may mean, what may cause them, and the best course to take would be appreciated.

Looks like what logwatch sends out after a box has been rebooted. Have you rebooted recently?

I haven't. This box has been up for 20 days. These entries appear every day.

Check /var/log/messages for the messages you see it should have the messages in context, post the content here.

If you look at the top it says
Code:
Dec  5 06:26:52 armed kernel: apache2: page allocation failure: order:3, mode:0x20


Which is the same as what you see here viewtopic.php?t=7805&start=15 might want to poke linode support and let them know you're having issues with the linode kernel they might be able to help.

Well, vm.min_free_kbytes = 8192 fixed that for me.
If you have disk thrashing problems, you might need even higher reserve for the incoming network buffer, but it'll be better to fix thrashing instead. ;)

Indeed, that is what fixed my issue.

This is an excerpt from the reply I got to my support request...

Quote:
You'll want to check the output of this command after your Linode reboots:

sysctl vm.min_free_kbytes

If it is lower than "16384", please raise it using the following command:

sysctl vm.min_free_kbytes=16384

You'll also want to add this line to your "/etc/sysctl.conf" file to make the change stick across reboots:

vm/min_free_kbytes = 16384


It solved the problem.

They did also recommend some MySQL and Apache optimization, but I had already done that some ago.
