From ac6325e4bbfa6ba9ace5c98787ef770325ddf051 Mon Sep 17 00:00:00 2001 From: Jacek Caban Date: Wed, 27 Sep 2017 20:18:07 +0200 Subject: [PATCH] rpcrt4: Wait for available pipe when connecting to busy server. It's most likely to happen when server just accepted another connection and didn't create a new listening pipe instance yet.
