In what respect is ulimit superior to well-tuned --max-child-processes? Recall we're looking at a runaway aggregate load, not a single-process problem. softlimit appears from the documentation to be mostly a DJB extension to the ulimit concept. Again, what does this have to do with excessive aggregate usage? At the present time the monitor is just a canary in the coalmine. A very healthy canary, I'd like to add. One that consumes zero sysadmin time. -- Dan Wilder
