Is there any harm in setting it higher than 16384 to 65536?

Right now I'm at vm.min_free_kbytes = 3429

I found this on the Fedora website, which is what I'm using on the Linode that went down.



Same error 16 days ago but that was "order:2" and today was "order:4" whatever that means. Looking at Linode graphs, just before the crash outgoing traffic was getting up over 5 Mbits/second (only around 3 Mbits/second in the morning) so I wonder if this "panic" was due to the server working harder. (Last night added more images to the website.)

Maybe this thread is old but it's nice to see other people were able to fix their "page allocation failure".

If you are still on our 2.6.x tree of kernels you need to upgrade. I also believe these issues are fixed in newer kernels. In addition to that, the 2.6.x line have a local root-escalation bug that's a bit concerning.

I'd suggest selecting the Latest 32-bit (or 64-bit if your OS is 64-bit) kernel in the Configuration Profile editor in the Linode Manager and then reboot.
