[BUG] User tools is aggressive in reserving memory on large machines #1406
Description
Describe the bug
It was noticed that the java process will be killed by the system; especially after we added the heap_min argument. This causes the tools runtime to be killed and we want to avoid that from happening on customer's side.
We should consider:
- Using a smaller amount of memory or calculate the heap size based on the available/free memory instead of total memory.
- Capping the number of threads to 3 is too conservative. We might want to do a different calculation.
