Steps to reproduce issue

I have not been able to reproduce this issue locally, but it has been happening since late last week (https://ci.ros2.org/view/nightly/job/nightly_linux_repeated/2279).

Expected behavior

CLI tests pass.

Actual behavior

CLI tests fail with something like:

[RTPS_TRANSPORT_SHM Error] Failed to create segment 56b71f66bffcdbb2: boost::interprocess_exception::library_error -< Function compute_per_allocation_extra_size
[RTPS_MSG_OUT Error] boost::interprocess_exception::library_error -< Function init

Logs are coming from within Fast-DDS.
