ProgrammingThis forum is for all programming questions.
The question does not have to be directly related to Linux and any language is fair game.

Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I don't know what this is but it might help to state what s/w you are using including versions.
Was your program compiled on the same system where you run it?
Do all forms of strace have this effect; even if you exclude read() and recv()?
Also before getting excited about possible kernel or library bugs I suggest a further look over the bounds checking of your code in case that includes a problem which behaves differently depending on the way it is called.

I don't care (In this specific case) about disconnects, signals or errors, I elect to simply bomb out and attempt to reconnect.
In normal cicumstances it stays on 24 hours a day, I am reading about 500 frames a second
each being written to file, about 800 files. I am using 3% CPU on a 500Mhz 512M virtual debian.
So I reckon I can program a bit
Only get weird reads under gprof on linux, without profiling it's fine.
I think it's likely static/shared library issues with gprof.
