limit datasize

[Giuseppe Pagnoni]

Dear all,

I am running into a memory problem when using large datasets.  The  
limit command shows:

cputime      unlimited
filesize     unlimited
datasize     524288 kbytes
stacksize    65536 kbytes
coredumpsize unlimited
memoryuse    unlimited
vmemoryuse   unlimited
descriptors  11095
memorylocked unlimited
maxproc      5547
sbsize       unlimited

however, /etc/login.conf shows that the default setting is "unlimited":

default:\
         :passwd_format=md5:\
         :copyright=/etc/COPYRIGHT:\
         :welcome=/etc/motd:\
         :setenv=MAIL=/var/mail/$,BLOCKSIZE=K,FTP_PASSIVE_MODE=YES:\
         :path=/sbin /bin /usr/sbin /usr/bin /usr/games /usr/local/ 
sbin /usr/local/bin /usr/X11R6/bin ~/bin:\
         :nologin=/var/run/nologin:\
         :cputime=unlimited:\
         :datasize=unlimited:\
         :stacksize=unlimited:\
         :memorylocked=unlimited:\
         :memoryuse=unlimited:\
         :filesize=unlimited:\
         :coredumpsize=unlimited:\
         :openfiles=unlimited:\
         :maxproc=unlimited:\
         :sbsize=unlimited:\
         :vmemoryuse=unlimited:\
         :priority=0:\
         :ignoretime@:\
         :umask=022:


Any suggestion on how to increase the limits?


thank you very much in advance
