   ## Troubleshooting
   
   The Compact C Type Format (CTF) has a 2^15 limit on types which can overflow, this prevents DTrace from
   working correctly.
   
   Check the number of types using `ctfdump` e.g
       ctfdump -S /netbsd
   
   Note the line which states `total number of types`, the value should by less than 32768.
   
   If overflow is not an issue, `libdtrace(3)` can provide some insight into what is going on via an
   environment variable. Define `DTRACE_DEBUG` before tracing.
   
        env DTRACE_DEBUG= execsnoop
