Hi!

I'm encountered the following errors while testing a module using
file:sendfile/2. It appears to be quite rare. 17 errors were logged for
11000 requests sent to the server. This is using "Erlang R15B (erts-5.9)
[source] [64-bit] [smp:4:4] [async-threads:0] [hipe] [kernel-poll:false]"
running on "Linux $(hostname) 3.0.0-1-amd64 #1 SMP Sat Aug 27 16:21:11 UTC
2011 x86_64 GNU/Linux".

=ERROR REPORT==== 29-Dec-2011::16:55:15 ===

stop_select was called for driver efile

The code is not merged into the main project yet and test is rather ad-hoc,
I'm defaulting to not providing it unless you specifically ask for it. Let
me know if you need and I'll write a summary for downloading and running it
if the error messages are not informative enough.
