Fair enough. I just tried here, and it works for me after increasing shmmax,
otherwise fails with the same error as above.

Looking at the code, it's a call to shmget with the actual number of bytes. I
suppose it could have been that other processes were using shared memory,
causing available shared memory to fluctuate (especually if close to the
shmall, though mine seems to be set to my whole RAM).
