High memory usage in v1.8.0 vs v1.7.2

I have a calculation that runs over two days. The memory usage stays below 3GB when using 1.7.2, but grows very slowly to over 30GB in 1.8.0 until the OOM killer terminates julia. It takes about a day to get there though. Is this a known issue? If not, I will try to debug it a bit more, although I dread the amount of time that it will take. Maybe I would also need suggestion how to get started with debugging?


You’re not the first: Resource usage in versions 1.7.2 and 1.8.0

Can you give more information about your code?

Many thanks for the link. The code that makes this occur is here:

the examples as described in https://github.com/rs1909/FMA/blob/master/examples/synthetic_ten_dimensional/README.md
are affected.

This is a large codebase, so it it is not obvious what to strip off to create a simpler testcase.
