You need to tune the SFSZLIM and HFSZLIM (in /etc/conf/cf.d/stune) to set the
required ulimit.  These values are tuned with a hex value of the file size 
in bytes (eg:  0x500000 is 5MB).  SFSZLIM is the soft limit specifying the 
largest offset in bytes of any single file that may be created by the process.
HFSZLIM is the max value of SFSZLIM.

You can overide this setting by using ULIMIT in /etc/default/login, but any
program that is exec'd setuid (ie: uucico), then ulimit will be set back to 
the system wide defaults defined by SFSZLIM and HFSZLIM.
