[dtrace-discuss] dtrace: error on enabled probe ID 1 (ID 31450: fbt:ip:tcp_rput_data:entry): invalid address (0x0) in predicate at DIF offset 36

I'm trying to set a point in which to run a series of commands when the TCP receive window size hits zero. I've found this works on my cluster node (118833-36) and an opensolaris host. But on other servers (T2000, Ultra 45 Workstation(127127-11), ) it does not work. 

fbt:ip:tcp_rput_date:entry
/((conn_t *)arg0)->conn_tcp->tcp_rwnd == 0/
{
  printf("pipeline full or window closed %d\n",
       ((conn_t *)arg0)->conn_tcp->tcp_rwnd);

/*
   stuff goes down here to stop the application and run
   a series of commands
*/

}

I get this error.
dtrace: error on enabled probe ID 1 (ID 31450: fbt:ip:tcp_rput_data:entry): invalid address (0x0) in predicate at DIF offset 36 

Any pointers or different approaches?

Thanks

Dave
