Subject: unexpected behavior of memory limits with XF86 3.3.1
Sender: owner-freebsd-stable@freebsd.org
X-Loop: FreeBSD.org
Precedence: bulk


The behavior of limits under XF86 3.3.1 is unexpected.  The "limit"s
are different under X than under a regular login session, and I do not
know how to change them under X.  I believe that this behavior is new
to 3.3.1/FreeBSD-2.2-stable (beginning when 3.3.1 was introduced), but
I am _not_ certain.

Has anyone else seen this behavior?  How do I get the behavior I
expect from X?  In particular, I need to increase the "datasize"
limit.

With a virtual terminal (or remote) login with csh:
(before unlimit)                     (after unlimit)                 
cputime 	unlimited            cputime         unlimited       
filesize 	unlimited	     filesize        unlimited       
datasize 	16384 kbytes	     datasize        262144 kbytes   
stacksize 	8192 kbytes	     stacksize       65536 kbytes    
coredumpsize 	unlimited	     coredumpsize    unlimited       
memoryuse 	30720 kbytes	     memoryuse       unlimited

I am using the sample login.conf, where the default is

default:\
	:cputime=infinity:\
	:datasize-cur=16M:\
	:stacksize-cur=8M:\
	:memorylocked-cur=10M:\
	:memoryuse-cur=30M:\
	:filesize=infinity:\
	:coredumpsize=infinity:\
	:maxproc-cur=64:\
	:openfiles-cur=64:\
	:priority=0:\
	:requirehome@:\
	:umask=022:\
	:tc=auth-defaults:

Thanks for any help.
