I meaned _potential_ ability of FreeBSD kernel to dump a process state (image) and when it is needed to restore process image back to the system and restored process should continue its executing. I didn't mean that application's object files should be relinked with some special library for checkpointing and restoring or an application should be designed for this (any modifications to existing application code). Of course it is clear for me that parent/childs relations can't be restored, as well as TCP connections, shared file descriptors, etc. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
