master_discovery memory leak #148

Closed amilcarlucas closed 3 years ago

amilcarlucas commented 3 years ago

I'm using the latest master version compiled on NVidia Jetson TX2, TX2i and NX. All three boards run on Ubuntu 18.04 LTS.

The longer the master_discovery service runs the more memory it needs. I suspect it has a memory leak!

atiderko commented 3 years ago

I run some tests with five ROS-Master's (five master_discovery, five master_sync and one node_manager) on Ubuntu 18.04.

I record the memory usage with psrecord.

With no changes on ROS-Master the memory usage increases slowly (almost an hour) until an upper limit (60MB) md_no_changes_in_ros_master

With a ROS-Node stop/start every 5 seconds the limit of 60 MB is reached faster and stay at this level. md_new_nodes_every_app_5s

I don't know exactly what the reason for the increase is at the beginning and whether it can be fixed at all.

Any progress on this? Please re-open it. After 40 days it increases from 40MiB to 423MiB
