Handling core dumps when process is holding boost interprocess lock
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.

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. --- Aaron Wright From: Rajalakshmi Iyer <raj@blismedia.com> To: boost-users@lists.boost.org Date: 09/28/2012 02:16 AM 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.
