I have a dedicated server with several virtual hosts on it (CentosOS 5). Most of content is served via lighttpd and just some via apache. The problem is that, while apache is working perfectly well, most of requests to lighttpd get timeouts. It worked just fine two days ago and there were no changes in code or configuration since then.
Server load is almost none, there are no errors in error log, and there's no increased traffic that we would notice.
any thoughts on this?
