Hi,
I have the same issue..
Maximum number of executor is set to 4 but there are 8-10 jobs running on slave machine.
Also, it happens with some of the machine while some of the machine have only 4 jobs whereas based on my understanding those jobs should be equally distributed to all slaves
I triggered around 3000 jobs using groovy script

Any kind of insightful knowledge is appreciated
Thanks,
Pranav
