It looks like you sent one ore more worker threads down a rabbit hole, to the 
point where they never make it back to the worker thread dispatch loop. 
Otherwise, the data collection would have stopped properly.

I don’t know of any recent or broken commits to the performance monitor plugin. 
Please look carefully at what you’re doing.

Subject: [vpp-dev] PerfMon Plugin Issue

Hi ,

I am trying to use the perfmon plugin for cpu-cycles event.
I am doing a continuous ping over a memif channel.

But, I am seeing that the command always return saying "Data Collection in 
progress".

DBGvpp# set pmc cpu-cycles
Start collection for 1 events, wait 1.00 seconds
DEADMAN: collection still running...
Data collection complete...

DBGvpp# show pmc
Data collection in progress...
DBGvpp#

Is there anything else I need to enable to use this perfmon plugin (or)  any 
known issue with recent commits.

Thanks & Regards,
Murthy
