Jenkins job is waiting for next available executor

Question

My Jenkins job is a Matrix build that should run on build machines labeled AAA and BBB. I have three build machines set up, each having label AAA and BBB. However, when I start the build job, the job does not execute. Instead, it goes to "pending - Waiting for next available executor" state. Why does not my job execute?

Answer 1

Check the slave node configuration. "Usage" field should be "Utilize this slave as much as possible" instead of "Leave this machine for tied jobs only".
