no. not seen it.
did you have a custom kernel with higher SHM settings on 6.0?
In any case, here is what you do:
in /etc/sysctl.conf add these:
kern.ipc.shm_use_phys=1
kern.ipc.shmmax=1073741824
kern.ipc.shmall=262144
kern.ipc.semmsl=512
kern.ipc.semmap=256
and in /boot/loader.conf add these:
kern.ipc.semmni=32
kern.ipc.semmns=512
the "sem" variables are really only needed if you want a lot of
connections, say > 100. The "shm" settings will cover you for tens
of thousands of shared buffers in postgres. You can obviously tune
those down to your taste.
