We recently para-virtualised a Xen / CentOS box which is running script
which uses fsockopen() to get a connection to an SMTP server.
Since the server changes it fails approx 50% of the time with:
"php_network_getaddresses: getaddrinfo failed: Temporary failure in name
resolution"
We've tried the solutions from Googling this error (such as restarting
Apache etc), but without success.
Why am I wasting your time with a Linux upgrade issue? Well,
gethostbyname() seems to resolve the IP every time. Manual lookups on
from the server seem to work with no problems.
Any help greatly appreciated. Should I perhaps be pointing this out on
the 'internals' list?
