   I believe those are both thread-local storage allocated by jemalloc, which is Arrow C++'s default allocator on Linux. I forget all the details but I think you can set `ARROW_DEFAULT_MEMORY_POOL=system` ( https://arrow.apache.org/docs/cpp/env_vars.html#envvar-ARROW_DEFAULT_MEMORY_POOL ) or use https://github.com/apache/arrow-nanoarrow/blob/main/valgrind.supp .
