dtrace: process aborted   
when I run the example from the wiki page
   dtrace -n "kercalls::enter { @count[execname,probefunc] = count(); }"
and let this run without doing ctrl-c I get an error message after some seconds
   dtrace:process aborted: Abort due to systemic unresponsiveness

whereas when I ctrl-c it, I get the expected output

Do you have a hint for me what's going wrong?

RE: dtrace: process aborted   
Are you running this in a vmware session?  I saw this too, recently.  I have
yet to nail it down though, but will be looking into it...
 
But basically is means that io-dtrace is not getting a chance to process
it's watchdog timer.
I believe Thomas set this up to be a pulse event.  I'll look into the code.
 
Thanks,
 
Colin

yep, I am running this in a vm ware session.
I will try this the next days on a native x86 installation

Re: dtrace: process aborted   
It appears to be a issue with the deadman timer being implemented as a user
thread,
whereas the check for deadman timeout is done at kernel time in the
dtrace_probe function.

Re: dtrace: process aborted   
Meh, it was bad timer creation code.  You need to set an initial value, even
for an interval timer. :-)
