When using monocle3 to calculate the pseudo time of 170,000 cells, an error is reported, and the error is *** caught segfault *** address 0x2b3ae695f5c0, cause 'memory not mapped'

Question

When monocle3 was used to calculate the pseudotime of 170,000 cells, cds <-learn_graph(cds)was run, but after calculating a few rounds, the error message was displayed as :

*** caught segfault ***
address 0x2b3ae695f5c0, cause 'memory not mapped'
Traceback:
 1: .Call("R_euclidean_dist", c(2.0837924345441, 2.29379465976953, 1.5256247692749, 0.333479963810365, 2.31289042347307, 2.32828339821469, 3.17704469089014, 4.50825967236
562, 2.6046687018261, 4.47783670677

If I run a small number of cells, I will not have this error, but every time I run a large number of cells, an error will be reported. Is this a software bug or is my operation error? How can I handle this error

This may be a general issue with R (see this example) or it is possible that you don't have enough memory to do this calculation.

Thank you very much!
