The only thread I see in archives is this one (in Russian):

http://nginx.org/pipermail/nginx-ru/2008-March/016620.html

There Igor explains that there are two possible causes:

1) (An unknown) bug in nginx.

2) Known problem in Solaris which sets errno to EINVAL (instead of 
ECONNRESET as others do and POSIX requires) when connection is 
reset by peer (i.e. your backend).

I believe (2) is much more probable (read: check your backend).

If you think that cause is (1) you may want to provide more 
debugging info, see here:
