As root: # su `perl -e 'print "A" x 100000000'` bash: /bin/su: Argument list too long This is on a Celeron 333 w/384MB of physical RAM. Red Hat 7.1 It took about a minute and a half to come back, and top says that bash was using 415MB of memory. I suspect you're just beating the crap out of swap, and need more RAM or process limits.
