What happened?

The origin web server does not have a valid SSL certificate.

What can I do?

Please try again in a few minutes.

If you're the owner of this website:

The SSL certificate presented by the server did not pass validation. This could indicate an expired SSL certificate or a certificate that does not include the requested domain name. Please contact your hosting provider to ensure that an up-to-date and valid SSL certificate issued by a Certificate Authority is configured for this domain name on the origin server.

When it comes to reclaiming node local memory, wouldn't it be useful to consider moving the pages in question to other nodes instead of discarding them (in case of unmapped cache pages) or paging them out (in case of dirty anonymous pages) as long as the memory utilization on any other node is lower than on the current node ?

Thank you Dr. Lameter for the easy to understand elucidation. My brain wasn't NUMA aware before reading this article and now it is happy and NUMA aware. This article will help me visualize the underlying memory model while writing applications for multiprocessor architectures.
