There are still some issues with memory tracking, but now with per-user
tracking:
executeQuery: Code: 241, e.displayText() = DB::Exception: Memory limit (for user) exceeded: would use 437.72 GiB (attempt to allocate chunk of 4200926 bytes), maximum: 437.72 GiB (version 20.6.1.1) (from 10.7.140.7:31318)
Although the server is mostly idle:
SELECT formatReadableSize(memory_usage)
FROM system.processes
┌─formatReadableSize(memory_usage)─┐
│ 289.28 MiB │
│ 155.75 MiB │
│ 0.00 B │
