[Boost-users] [interprocess] Lost communications and mysterious names

I'm using boost 1.46 on windows XP and I am having occasional issues with interprocess. Sometimes I lose communications between programs. I've located the directory where the files that enable the interprocess communication are created. Usually the files have the name I provide to the managed_shared_memory object in the code. However, when the problem occurs a file named something like "70C0A8E6490FCC01E55D313B550FCC01" appears. When the programs terminate this file disappears, while the normally named files persist. Why and where in the code do these files occur? Any hints as to what is going on?
