Hey @satishtaluru, does the error also include a line?

@satishtaluru Thanks for reporting, this is indeed a bug in the underlying react/socket component that will only be shown when using legacy PHP 5.

I've just filed reactphp/socket#230 to fix this underlying issue 👍 In the meantime, we highly recommend using the latest PHP version in which case this error will not be shown.
