Subject: [-next regression] TCP window full with EPOLLWAKEUP
Date: Sun, 20 May 2012 00:06:57 +0200 [thread overview]
Message-ID: <4FB81981.3050509@suse.cz> (raw)
Hi,
a bisection shows that with the following commit from -next:
commit 4d7e30d98939a0340022ccd49325a3d70f7e0238
Author: Arve Hjønnevåg <arve@android.com>
Date: Tue May 1 21:33:34 2012 +0200
epoll: Add a flag, EPOLLWAKEUP, to prevent suspend while epoll
events are ready
====
one of mono programs I use stops receiving data from the network.
Wireshark shows that the TCP window of a connection is filled. This
means the program does not read the data fast enough after requesting
the data.
If I revert that commit on the top of -next (20120518), everything works
as expected.
regards,
--
