Robot Name 🤖

ergoCub 1.3 S/N:002

Request/Failure description

I opened the issue here just to keep track of it.
During the iros2024 demo we closed the walking controller that uses shmem for the remote control board connection and the wbd external contact force port connection.

This is the error

I provided a fix (or workaround, not sure) at https://github.com/traversaro/yarp/tree/fixshmem, if this happens again feel free to cherry-pick the fix traversaro/yarp@bff2606 on top of the yarp branch used on the robot. @S-Dafarra @GiulioRomualdi

I opened robotology/yarp#3147 to fix the problem with shmem upstream in YARP. I also found and fixed the problem with unix_stream and multipleanalogsensorclient, so if we have problems with shmem we can also test again unix_stream, if you want to cherry-pick the changes the related commits are:
