Hi,

I have been using plockstat to analyze user-space lock-contention for multithreaded programs.
I am also optimizing the performance of those programs using larger pages (using ppgsz(1)). 
I am unable to get anydata (output) from plockstat(1) when I run the program along 
with ppgsz. However, getting output without ppgsz. Moreover, there are no error/warning messages in 
the earlier case.  

Could you tell me what is happening here, please?

The following are the command line argumenets:

$ pfexec plockstat -C ppgsz -o heap=2M <my-program>
