You are using the sockets provider. Could try set <code>FI_PROVIDER=tcp</code>​ to see if it makes a difference?<br>

Meanwhile, if you can get a small reproducer – with the sockets provider or any provider, I'll try to debug it. It is difficult to guess the true source of the issue without a reproducer.</div>
