Hi all,

For several weeks, we have randomly every 2/3 days the following error in php scripts that occurs:

php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution

It lasts a minute or two and then everything goes back to normal.
Since yesterday we have the same problem on another server under Plesk. These two servers are installed then 2 years. No problems so far and we haven't done anything special for months.

Any idea of the origin of the problem?
Nothing changed in the firewall or resolv.conf.

Thank you.

Erwan
