Eric,
When does this occur? Any specific situation ?
What is your VM setup ? (mem,cpu,os).
Thanks

Peter,
The problem can be reproduced on a VirtualBox system (Host is a debian sid).
This is linked with a usleep(10) call in the flow manager. I've proposed a patch to Victor and Anoop which are currently reviewing it. The patch is attached to this comment.
