[Boost-users] [Interprocess] hang locking p_hdr->m_mutex

I've got my machine (Win 7) into a state where using a message queue results in a hang. More specifically, calls to: scoped_lock lock(p_hdr->m_mutex); hang forever. As a bit more background, there's a message queue that holds up to 5 x 1024 byte messages, and I believe currently has 2. I'm having a hard time verifying that because calls to get_num_msg() hang trying on calls like the one above, but that's what I see when I look in c:/ProgramData/boost_interprocess/20110816195406.550541/CliIPC. I have feeling what happened is that some process that was using the message queue got terminated while holding the p_hdr->m_mutex. Does anyone have any suggestions for recovering from this? I'm using version 1.47. Thanks for your help. -DB
