I actually ran into the same issue. I solved it by using file locks,
instead of named mutexes, because the file lock will be released when the
process crashes.

Subject: [Boost-users] Handling core dumps when process is holding
boost interprocess lock
Sent by: boost-users-bounces@lists.boost.org
Hello,
I am working on application where several multi-threaded processes are
attempting to acquire a lock on the shared memory files managed via boost
interprocess.
It appears that if one of these processes dumps a core while holding a
lock on the shared memory file, all the other processes end up waiting for
this lock to be released.
Any ideas on how this can be overcome? I want to ensure that when a
process that is holding the lock dies, it should ensure that the lock is
released.
Thanks,
Raj
