Should mutexes be used to ensure concurrency, while using POSIX message queues?

fixed the issue. Will look into that further This is similar to Is msgsnd() thread- and/or process-safe? . The short answer is - it's already thread-safe, so there's no need to use mutexes.

What have you used sysv/posix message queues for?

Hope this helps I had a series of commands that needed to be executed in order, but the main program flow did not depend on their completion so I queued them up and passed them to another process via a System V message queue to be executed independently of the main program. Since message queues provide an asynchronous communications protocol, they were a good fit for this task.
To be honest, I used System V message queues because I had never used them before and I wanted to. I'm sure there are other IPC methods I could have used.

around this issue One thing you can try is to see whether you can go by using a unix domain datagram sockets instead of posix message queues, in particular SOC_SEQPACKET variety of those:

I wish did fix the issue. I've been working remotely with POSIX message queues for some days. Now I want to do it in my own PC but I've found that there's no /dev/mqueue folders where queues are created; which means that I don't know where they are (of whether there are or not), so I can't access there to delete them in case of an unexpected end of my program.
