RE: core_dump_dest = /dev/null?

Hello Heidi,

/dev/null is a device special file serviced by a VERY lightweight pseudo device driver. There is no risk of buffer overflows, hangs, system panics or the like.

Well, /dev/null isn't exactly the garbage bin of the universe. It is more like a buffer.

You can put alot into it, but it can play havoc on your system. Especially is there is are occuring error that streams constantly to the buffer. It can cause your machine to hang or reboot.

My advice is that you can use it for small things but avoid dumping large amounts of data to /dev/null
