See the documentation in crashme.txt or read this document for a description of command line arguments to this program.
crashme: Create a string of random bytes and then jump to it.
crashme [+]<nbytes>[.inc] <srand> <ntrys> [nsub] [verboseness]
Suggested test: At least let the thing run the length of your lunch break, in this case 1 hour, 10 minutes, and 30 seconds.
crashme +2000 666 100 1:10:30 2
Also, it may spend more time trapping and less time computing random bytes by using these arguments:
crashme +2000.80 666 100 1:10:30 2

Crashme V1.0 {1000 20 200} used to down the SUN 4/110. V1.2 does not crash SUNOS 4.1.1 on the same arguments. Although using the extra argument for subprocesses it will crash, with the console reporting: "Bad Trap, Bad Kernel Read Fault, Bus error. Reboot"
Script means invoking file with many calls to crashme such as this:
#/bin/csh
crashme 1020 234 500 &
crashme 394 38484 5723 &
crashme 3784 474 474 &
crashme 437 4747 38 &
crashme 47848 4745 123 &
crashme 4747 4747 3463 &
crashme 474 46464 262 &
crashme 37 3644 3723 &
crashme 374 46464 22 &
crashme 3747 464 363 &
crashme 347 4747 44 &
crashme 37374 374 66 &
crashme 3737 474 4444 &
The 4-argument case of crashme could likely do as well as executing a script.
25-SEP-2005 GLO - Add a #define for Solaris
28-SEP-2005 GLO - Minor edits to improve readability for me & no one else
03-OCT-2005 GLO - Reformat the code for additional white space. This is
for my readability and no one else's.
14-JUN-2006 GLO - Modifications to comply with 'gcc' (Linux/Posix) signaling
standards
29-JUN-2007 GLO - For Solaris X64, add a "#define solaris"
For -Xc add extern int kill(,) even though signal.h
defines it
