platform info    : Linux-5.10.104-tegra-aarch64-with-glibc2.29

Steps to reproduce issue

I started multiple nodes, and after running normally for a while, some topic data suddenly stopped.

Expected behavior

everything ok

Actual behavior

When checking the message frequency with ros topic hz, an error occurred:
[RTPS_TRANSPORT_SHM Error] Failed init_port fastrtps_port7425: open_and_lock_file failed -> Function open_port_internal
Then, I checked /dev/shm and found only "fastrtps_port7425_el" but no "fastrtps_port7425". After deleting all files in /dev/shm and restarting the process, it recovered.

Additional information

The communication between different hosts was not affected. It seems that the shm communication was abnormal.

Do you happen to use docker container?

[rty813]

Yes, it runs in a docker container. But I set some settings related to shared memory in docker-compose:

network_mode: host
ipc: host
uts: host
privileged: true
container_name: prd_foxglove
restart: always
ulimits:
  core: 0
