Research direction

Start by reproducing cbench in throughput mode with separate cbench and controller servers, then inspect msgbuf.c:109 and the msgbuf_grow allocation path. Done means identifying why the allocation fails in this setup and preventing the assertion or documenting the required conditions.

Written by the indexing model from the issue text.

Description

I got that message when running cbench on throughput mode: cbench: msgbuf.c:109: msgbuf_grow: Assertion `mbuf->buf' failed.

I'm using two separate servers, one for cbench and another for the controller.
