[ros-users] Navigation stack not working

[Prasad Dixit]

I resolved the issue by changing /base_link in my odom, global/local costmaps
and an AMCL to /base_footprint
but i ended up at costmap timeout issue where my update frequency for odom
is sufficient to 20 Hz.

I get below warnings and the system consumes almost memory which slows down
it and further stack stops working.

I had similar issue last time which was solved by updating frequency. I
tried this time but didnt work.
anyone has any solution?
