open_or_create flag doesn't works in boost library shared memory.

Question

Hello Everybody, I am using boost library for sharing maps from one process to another using Shared Memory concept. Its working fine for me for the first time, but if the shared memory object is already present, then it just crashes. So, I have modified my code to use open_or_create flag and am expecting it to work, but still it crashes mentioning that the shared memory object is already present. I don't want to delete the shared memory but just in case, if I need to re-use the same, then its a problem.

If anybody have a shared memory to work for the re-use, please help me in this regard.

Thanks, Neelesh K J Jain.
