mapOtimization is killed while trying to save data #19

Hi,

Thanks for your addition!

When I enable the save tool it seems to save poses and everything else properly, except for the cloudGlobal.pcd. I'm guessing it might because of this:

****************************************************

Saving the posegraph ...

****************************************************

Saving map to pcd files ...

[sc_lio_sam_mapOptmization-4] escalating to SIGTERM

shutting down processing monitor...

... shutting down processing monitor complete

done

It appears the saving of cloudGlobal.pcd is interrupted as I cannot open it in CCviewer and this message is reported:

[pcl::PCDReader::read] Number of points read (6881489) is different than expected (42642378)

If anything else is needed, please let me know.

I'm having the same issue, were you able to figure out what caused it?

My guess is its an issue with GTSAM. I had to use gtsam 4.0.3 to get LIO-SAM to work with noetic.
