Memory Leak? #21

Closed griz1112 closed 4 years ago

griz1112 commented 4 years ago

If you leave loam-livox running for about an hour it will eventually take up all the memory and swap and crash. This is on a nvidia Xavier which has 16Gb of ram. Ubuntu 18.04. Easy to see with jtop. It takes a long enough period of time to crash that it isn't really going to effect my testing that much but I thought you might like to know.

The memory of 16Gb is too small for one-hour running... Can you install more memory on your platform, otherwise, you can turn off the "loop closure" for memory saving.

Its a jetson Xavier so the memory is fixed. No biggie my rover won't run an hour so won't impact me. Just saw that it did crash eventually so I thought you might not know.
