[SAC] server overload again

Folks,

Both, the server overloads are coming close together today.

This time there was no sign of backup activity (note that last night
rsync was running doing our non-dsmc backups).

This time I've tried apachectl graceful and a minute or two later I
inspected the server-status report to see which requests were still
unhandled (in the "G" shutdown pending state). I have attached the
report.

I'm particularly surprised by the number of GET /tyler/feed requests
still pending. I assume these are RSS queries against Tyler's blog.
Could these be expensive? Why would they be slow to recover?

Best regards,
--

Good question :frowning:

They are generated by drupal on the fly, not sure if they get cached or not.
But that'd be the case with the 'events' and 'news' feeds we have as well.
