I run a medium size WordPress-powered blog (ca. 10K visitors/day) on a VPS running CentOS (more information can be found at the hosting company's site [url removed, login to view]).
Some unidentified problem(s) is/are causing the site to crash regularly, typically once a day. Restarting the server solves the problem, but I would like a more permanent solution.
I am looking for someone who can identify the problems and fix them -- whether they be due to WordPress, the plugins used, spam-comments-leaving bots, the server/APACHE's configuration, etc... Because the blog has been on the receiving end of DOS attacks in the past, I would also like to find someone who can provide ongoing assistance with any other issues as they arise.
