dtrace discuss - Jul 2006 - DTrace bailing out on x86/SMP snv_42

Hi,

I''m having some weird problems with DTrace on my dual core amd64
machine.
Given the following command:
% /usr/sbin/dtrace -n ''syscall:::entry { @[execname] = count();
}''

Dtrace bails out with the error message "dtrace: processing aborted: Abort
due to systemic unresponsiveness".
This is quite untrue, the system is next to idle.

However, if I take one of the processors offline, everything works as expected. 
Any ideas?

saint ~ % /usr/sbin/dtrace -n ''syscall:::entry { @[execname] = count();
}''
dtrace: description ''syscall:::entry '' matched 229 probes
