Hi,

I'm working on a problem with Apache 2.2 + PHP on FreeBSD 6.1 x86

Recently, we've upgraded from Apache 1.3 to v2.2 , and since then PHP is =
unable to resolve hostnames unless they're specified in /etc/hosts . The =
error we'd get would be:

php_network_getaddresses: getaddrinfo failed: hostname nor servname =
provided, or not known in /home/username/public_html/testphp.php on line =
2

This is for a simple <? include(http://www.google.com); ?> function. We =
know it is not a DNS problem, because if PHP is setup as a CGI function, =
it works fine. It is only in DSO mode that PHP malfunction like this. =
We're also having no issues with our resolver for mail, ping or any =
other services.

Some people were pointing out that this is a fault of FreeBSD reaching a =
maximum number of file descriptors. Others said this can't be resolved =
until upgraded to FBSD 6.3 which we are not planning to go through. =
There are several hundred domains hosted on the server, but all was =
working fine with Apache 1.3.

 Our VNODES are a bit high, but haven't seen any errors:

server# sysctl kern.maxvnodes
kern.maxvnodes: 100000
server# sysctl vfs.numvnodes
vfs.numvnodes:  84805

server# sysctl kern.maxfiles
kern.maxfiles: 65536
kern.maxfilesperproc: 32767

Anyone be able to guide me in the right direction here?

Thanks,=20

Tamouh
