Hi,

Yes... my bad.. by 3D mapping rate I meant odometry rate(the fps shown at bottom left corener of 3D map window in the gui).

I tried the commands. All of them returned the same error i.e. segmentation fault(core dumped) (except data_recorder which I dont have installed).
I started the node with gdb. It certainly gave more insight into the error -

... logging to /home/ubuntu/.ros/log/7a9f93dc-1dd6-11b2-bbb2-b827eb068306/roslaunch-ubuntu-3151.log

I came across an interesting thread about the illegal instruction error at this github issue (but the file where this happens is different for our case).

I will search more about the issue tomorrow and edit this post if i get something useful. Right now, signing off. Its already 3am here.

Thanking You,
