protect(1) ?
Of course. I really do not understand how google hides the man page
from me.
Thanks, and sorry fot the noise.
The OS trying to kill a process is probably not what you want. So when you
protect(1) postgres the OS will kill another process, which I hope is not
running without reason.
My advice would be to
- or increase your swap space
- or tune postgresql to use less memory
- or limit tmpfs (tmpfs uses swap if RAM is short)
- or tune zfs to use less memory

Ronald.
