[Boost-users] [shmem] error while closing the segment

Hi, I get an error when I try to close the shared memory segment. My 
destructor calls simply mysegm.close(). I get the message below, but I can't 
interpret it so that I can do anything with it. It happens only if before a 
child process, that works in this segment too, is terminated erroneous and 
subsequently a faultless run was done. But to close the segment should be 
possible after errors too and at any time. When I restart my application 
without deleting the segment by hand it hangs in the constructor and I can 
wait forever, without any message.

Thanks a lot, Sascha
