Hi Team, 

I have installed throttle concurrent build plugin recently to run only 3 jenkins pipeline job in parallel and the remaining should wait in queue. When i trigger the job manually it works as expected but when I trigger the throttle job from another jenkins job using curl command or jenkins trigger parameter the throttle build job doesn't wait in queue and job is not even getting triggered if already 3 jobs were running. The return code using curl command is 302 and please find attachment for the same.
