--- Comment #25 from ---
Perhaps, we're seeing the error even in the balancer SHMs as well as the worker
SHMs and the balancer SHM already uses conf->id as a distinguisher.

For this balancer (not worker), even with Jim's change, we saw the following.
Summarizing first

12:26:41  - attach found and attached to slotmem-shm-p701d8bbe_0
12:33:51  - SIGHUP
12:34:54  - create (not attach) fails to find slotmem-shm-p701d8bbe_0
12:34:54  - create fails to create because the SHM key/segment is still in the
12:38:54  - create (under a new PID) fails to find slotmem-shm-p701d8bbe_0 but
successfully creates it, presumably because all attached processes detached

Why didnt the generation change? it was zero before and after the HUP.
