You're right and it is strange. I don't know why this would happen but some things that come to mind are: * Does lighttpd have some kind of status page or a diagnostic utility to show you the states of FastCGI processes? * Does lighttpd have a facility to "reap" old PHP processes? For example, mod_fcgid has a maximum lifetime setting for FastCGI processes. * You could try sending a SIGABRT to the php-cgi process to get a core dump and inspect it. Without debugging symbols it will probably give you the name of the function it's been waiting in.
