Description

Lenni's in the midst of investigating.

Reproduction:

• Lots of DDL (create table), preferably in parallel, to speed things up.
• I was attempting to load ~100k tables.
  Observation:
• tcmalloc.total-bytes-reserved monotonically increases till the Catalog Server exits with an OOM error.

As a side note, I've been able to hit this locally as well.
