getrlimit for an arbitrary process?

getrlimit for an arbitrary process?

[Ville Herva]

[I did try google, but wasn't lucky, so...]

Is there a way to query/set getrlimit/setrlimit for an arbitrary process?
Not that I absolutely need it, but it would be nice to know if a daemon
really has resource limits in effect.

Couldn't find it under /proc, at least on 2.4.x.

(A 2.4.21-pre4aa3 server just locked up hard rather horrendeously when
SpamAssassin spamd decided to fork a couple of thousand processes... Looks
like I need sprinkle ulimit lines all over /etc/init.d/*.)

Nope, rlimits only work on the current process
(and a few of them work on the current UID).

Good idea for 2.7, though we might as well go
all the way and set up more arbitrary resource
groups.

Take a look at http://ckrm.sourceforge.net/  ;)

Yep.

Interesting. So is linux-vservers (and a bunch of other projects). I hope
the common denominator of these can be distilled out and soaked into the
mainline kernel...
