Had some memory issues on one of my hosts. After n number of httpds fork(), you may find that the host may slow to a crawl. The decision here is whether to deny connections in order to improve performance for the remainder, or to let all of the connections degrade from increased I/O as the OS exercises virtual memory. If you choose to deny connections, you can alleviate the load by lowering MaxClients in the Apache configuration; pick a number that, when multiplied by the amount of memory used by each process does not exceed the amount of RAM installed. If this number is too low, buy more RAM. You can tweak some other settings further, but your capacity needs to scale meet your load.

Now, as to that load. It was unusual. Looking at the it over the past month, you can see a significant increase though not enough to show as a memory shortage until this past weekend. What's so popular about someone's personal webpage? Did the InstaPundit join Prodigy?

Teach Yourself Network Troubleshooting in One Post

Regarding Sams Teach Yourself Network Troubleshooting in 24 Hours, Second Edition: You don't need 24 hours. You need to remember that networking is just some machines talking to each other. Is the power cable plugged in to the computer? Is it plugged in to the power outlet? Is the computer on? Is the network cable plugged in to the computer? (No? Must be a wireless network.) Is there a link light? Is the cable plugged into the wall? Can you look up the name? Can you ping that box? Can you talk to the same service on any other box? Do you have the phone number for Operations? Can you hear me now? Good.

The Worship of Bundles of Sticks

Rebecca Blood, whom I do not read regularly because she has no RSS feed, points to some pointers to some articles on fascism by David Neiwert, author of In God's Country: The Patriot Movement and the Pacific Northwest. Fascism is on my mind again after finishing American Empire: The Center Cannot Hold.
