Try to see what is in the temp dir used by USA (tmp/USA and /tmp/SA).
I all cases you should be ok deleting all files in both directories.

I've noticed also that sometimes I've got something like this:
/etc/cron.daily/run_usa:
/usr/sbin/USA: [: too many arguments
I have several servers in the same situation
