Can you include a heap profile? It should have been dumped in the log directory.

[jordanlewis]

Oh, oops, I didn't realize this was not in the database repo.

[BramGruneir]

@glennfawcett, Please try this again with the latest version. I'm not sure if we need to figure out some memory accounting, but I can if needed.

[robert-s-lee]

@glennfawcett added TPCC instruction on add-tpcc-example branch. can you check against your test steps

[BramGruneir]

This is quite old. Closing.
