On my box the values defined for the kernel are as follow:
options SHMMAXPGS=65536 #For postgreSQL
options SEMMNI=40
options SEMMNS=240
options SEMUME=40
options SEMMNU=120
If my memory serves me right these values were suggested for PgSQL in
FBSD or Postgres documentation.
and the corresponding sysctls:
kern.ipc.shmmax: 268435456
kern.ipc.shmmin: 1
kern.ipc.shmmni: 192
kern.ipc.shmseg: 128
kern.ipc.shmall: 65536
your kern.ipc.shmall seems a bit low comparing to my setup, maybe the
culprit is there. You can tune that sysctl at runtime, try if giving
it higher value helps.
