Fatal exception within EIO Adapter eio_poll handler

[lucasnetau]

Within the Adapter.php closure defined in function executeDelayedCall

function ($data, $result, $req) use ($deferred, $errorResultCode, $function, $args) {
            if ($result == $errorResultCode) {
-->                $exception = new UnexpectedValueException(@eio_get_last_error($req));
                $exception->setArgs($args);
                $deferred->reject($exception);
                return;
            }

I get the following fatal exception on occasion.

Line: 401
Message: Class 'React\Filesystem\Eio\UnexpectedValueException' not found
Trace:
#0 [internal function]: React\Filesystem\Eio\Adapter->React\Filesystem\Eio\{closure}(NULL, -1, Resource id #42794)

#6 {main}

I do not have a way of reproducing this expect running the script for a long time.

Sorry, invalid, seems to be an opcache error.
