Hello guys, I have noticed today that I have another problem possibly related to this issue. I am running lighttpd+php-cgi in a jail on a 7.0-STABLE system as of Thu Aug 21 10:59:02 CEST 2008. The problem seems to be that lighttpd stops serving the pages, however I haven't had time to dig into this any more closer, but I have found out that there's a lot of connections to the lighty when it seems to be "dead". May be it does not close the connections properly?? The only common thing here is that that this jail is serving a page where a lot of image uploading happens.
