This was observed in the Bugfest Q12020 Enviroment. While trying to download Instance UUIDs. The module runs OOM possible because of the large number of Instance UUIDs(tried to download 1159087 Instance UUIDs ) that we are trying to download and all the jsonb being loaded into memory
Looks related to https://issues.folio.org/browse/RMB-581, which has clear analysis of the possible issue
