Subject: No timeout with no portmap
Date: Wed, 28 Jan 2004 19:00:16 +0100 [thread overview]
Message-ID: <20040128190016.0ea8334b.ak@suse.de> (raw)
I just tried to mount a NFS file system on a system with no local portmap running.
mount ended up in an endless uninterruptible sleep in xprt_transmit.
It only recovered when I eventually started portmap
Shouldn't there be a shorter timeout for this?
Happened on 2.6.2rc2 on AMD64.
That was the hanging mount:
