I'd also strongly suggest not typing "exit" into kdb, the Solaris debugger when it is in write mode. It sets the global pointer for exit (the libc function) to NULL and the whole system will crash a few seconds to minutes later when the next process exits.

(It's not uncommon to use this tool to reconfigure some configuration values at runtime)

At least not on Solaris 10 or any of the open source derivatives. Seems it was special cased at some point in Solaris 11.

Had to make that mistake 2-3 times before I finally realised what I was doing to crash it given the slight delay.
