Getaddrinfo() thread failed to start

Hello,

my PHP version 8.1

since 05/05/2026, I have random errors [Monetico] Curl error 6 - getaddrinfo() thread failed to start in PrestaShop, even in maintenance mode, so without client connections.

last week, this issue could last 1 hour. Today, it lasts 1‑2 minutes then disappears but is much more recurring.

After creating a test script:

$ch = curl_init();
curl_setopt_array($ch, [
    CURLOPT_URL => 'https://google.com',
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_TIMEOUT => 10,
]);
curl_exec($ch);
echo curl_error($ch);

when the problem occurs, the script also displays "getaddrinfo() thread failed to start" during a bug reported by Monetico, PayPal... So this does not come from the module or payment modules but from PHP on the OVH side.

Has there been an OVH security action causing this problem?

How to fix it or is it already being resolved?

Thank you.

It could be that an execution limit has been tightened (ulimit). Maybe a more powerful plan is needed?

@LibreMaster Indeed, there may be a link between resource‑overrun spikes and this error. My logs also showed many calls to the Packlink module that was transitioning (so duplicate) to the DPD module. Its deactivation seems to have removed the resource overruns.

Since my message, there have been no more overruns and no more getaddrinfo() errors. A day apart, there is a correlation, but with the holiday, less traffic, so no errors either…

What surprised me is that even in maintenance mode we still got this error for an hour while traffic had dropped long ago. But perhaps OVH blocks resources longer than the overrun peak.

I am indeed thinking of changing the plan, but first I wanted to understand and fix the root cause because traffic alone does not explain it.
