Hi,<br><br>I found a problem that seems to be an issue in boost.interprocess (1.41):<br><br>I was using managed_shared_memory (not managed_windows_shared_memory) and all was going fine until the day I run my applications on a virtual machine.<br>

The problem is that some applications were randomly not able to attach the shm previously created and the error was: &quot;The system cannot find the file specified&quot;.<br>I found that in fact the folder (under ...All Users\Application Data\boost_interprocess) where the shm file was being looked for was not the same as the folder where it was created.<br>

<br>Is it possible that the algorithm used to build the name of the folder &quot;thinks&quot; for some reason that there was a system restart ?<br><br>Cheers,<br><br>Rui<br>
