Subject: Reading from fuse pipe fails with EBADFD
Date: Tue, 27 Nov 2018 20:26:39 +0000	[thread overview]
Message-ID: <8736rmb728.fsf@vostro.rath.org> (raw)

Hi,

When testing FUSE under heavy load, I am occasionally getting EBADFD
errors when reading from the fuse pipe.

Does anyone have an idea what might cause this, and how to debug it
further?

Unfortunately I can't tell if this happens upon read() or upon
splice(). I've extended the code now, so the next time it happens I will
be able to tell.

I am testing with kernel 4.15 from Ubuntu Bionic.

So far this has happened twice in about 3 hours of testing. For the
testing, I am repeatedly running the same 3 workloads, without
remounting. Each workload takes ~ 15-30 seconds.

Best,
-Nikolaus
