The following reply was made to PR kern/22826; it has been noted by GNATS.

Oh, I didn't know that. (In fact, it's a bit tricky to correlate the limits described in setrlimit(1) with those handled by the (u)limit command in various shells. More to the point, however, in my experiment I used both -d and -s as well as -m, and still the process grew without bound. I'm sorry, I should have mentioned that. - Harald To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
