 New Comment:

I haven't had problems with different kernels. Only the combination of
x86_64, stream_socket_client() or stream_socket_server(),
stream_select() and PHP OpenSSL-support seem to reproduce this every
time.

i experience a similar problem since the latest standard kernel update
with yum (host.domain.com point to the main server IP) :

<?
$url="http://host.domain.com";
$fp = fopen ($url,"r");
$buffer=fread($fp,8192);
fclose($fp);
echo $buffer;
?>

booted with kernel-2.6.11-1.14_FC3 package: OK
booted with kernel-2.6.11-1.27_FC3 package: NOT OK (timeout)

NOTE: but only if "host.domain.com" point to the executing host itself
- same with "localhost" - for all others it seem to be fine

Also trying to compile valgrind on x86_64 results in:
checking for a supported CPU... no (x86_64)
configure: error: Unsupported host architecture. Sorry

I could, but I get this:
valgrind: Can only handle 32-bit executables

On a 32bit executable and with openssl stream_select() worked ok. On a
64bit PHP executable it doesn't.

Can you now check it with valgrind, please?

Ok the latest snapshot compiled cleanly on x86_64. The stream_select()
bug is still present in the latest snapshot.
