I agree with Kevin. That brecv problem is probably the root problem
that led to the flow protocol errors. I can't find that particular
error message in 2.7.1 or trunk though, though. I know it used to be in
there but was updated at some point.
If this is a reproducable problem, you may be able to simply take
src/io/bmi/bmi_tcp/sockio.c from trunk and drop it in place in your code
to see if that fixes it. There have been some updates here and there
regarding how it handles blocking and nonblocking calls, but I believe
it is API compatible with 2.7.1.

Elaine,
I think this error means that some code is trying to perform a
blocking read on non-blocking socket and there is no data present. You
are running 2.7.1?

Subject: Re: [Pvfs2-developers] Is there a patch for flow proto errors?
Hi Elaine,
That error code corresponds to a broken pipe error from TCP, so it is
probably a side effect of something else going wrong (for example,
possibly a server or client crashing, or a peer hitting some other error
and closing the socket unexpectedly).
Are you seeing this on the server side or the client side?

I am getting the following errors while working with PVFS 2.7.1 code. I
have found a couple of old threads from the mailing list that report
these same errors but I can't find the solution. Can anyone point me to
a patch that fixes it?
