Strange Server Problems
Hi All, I have a dedicated server running FreeBSD 7.0 release, it has been running well for two months. Suddenly, some websites stopped responding, all websites hosted on this server are simple PHP sites, if one site is working, all of them should work. I checked the bind/apache/mysql, everything is fine (otherwise no websiets would be working). Could anyone please give me some hints? Where should I start to look into this problem? Thanks, Kevin ___ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
Re: Strange Server Problems
Thanks for your reply, Joe! There is nothing in either system log or Apache log files. Apache doesn't seem to have got the requests at all. Very strange.

Re: Strange Server Problems
Telnet to port 80 and do an http 1.1 get request for both a site hostname that works and one that doesn't. What do you get as output in each case? GET / HTTP/1.1 Host: www.hostname.com Also, if nothing is showing up in the logs at all I wouldn't expect it to be php problem, but you might test that too. Put a simple static html page in one of the websites that has stopped responding, see if you can pull that page. - Original Message - From: "Kevin" To: Sent: Saturday, February 28, 2009 10:35 AM Subject: Re: Strange Server Problems > Thanks for your reply, Joe!

Re: Strange Server Problems
Hi Boris, Thanks for your reply! With Joe's help, I narrowed down the problem to IP configurations, it turned out to be my ISP's fault, they changed something on their side and caused some IPs to stop working, the requests didnt' reach the server. I convinced the support to report the problem, their networking stuff fixed the problem. Kevin On Sat, Feb 28, 2009 at 12:47 PM, Boris Kochergin wrote: > Kevin wrote: > >> Thanks for your reply, Joe!

if_clone_destroyif() should check that ifp is on ifc->ifc_iflist
but it doesn't.
Probably the following patch may fix this problem, but I fear that
there might be another race between a thread accessing the ifp members
and a thread calling if_clone_destroy().
