yes, thank you.

Would you also know what this mean then:

Apr 26 16:37:45 mech-as28 kernel: pid 33752 (syscall), uid 1001: exited on signal 12
Apr 26 16:37:45 mech-as28 kernel: pid 33757 (syscall), uid 1001: exited on signal 12
Apr 26 16:37:45 mech-as28 kernel: pid 33751 (syscall), uid 1001: exited on signal 12

Does this mean that the program, syscall in this case,
tried to invoke a system call which doesn't exist?

Could this be because I'm running it on ia64, whereas it's
likely to have been written for i386/amd64?

Just to clarify, I'm running stress2:
	http://people.freebsd.org/~pho/stress/

on ia64 -current box.

many thanks
