[Libguestfs] nbdkit error: "write reply: NBD_CMD_WRITE: Broken pipe"
Hi,
I am developing a new nbdkit plugin, and occasionally I am getting errors like
this:
`nbdkit: s3backer.8: error: write reply: NBD_CMD_WRITE: Broken pipe
nbdkit: s3backer.15: error: write reply: NBD_CMD_WRITE: Broken pipe`
(where "s3backer" is the plugin name).
I am not sure what to make of these. Can someone advise?
Looking at the nbdkit source, it looks to me like these are generated when there
is a problem sending a reply to the nbd client. On the other hand, I am using
the standard 'nbd-client' program through a Unix socket, so I'd
think this should not result in errors...?
Best,
-Nikolaus
