Jenkins not executing jobs (pending – waiting for next executor)

Problem

In jenkins while executing multiple jobs in parallel. Upto a specific number of jobs are running in parallel, but beyond that, if we submit any job, it was going to waiting state.

Solution

In this case, jenkins is executing jobs in parallel upto some number. That means somewhere we need to increase the parallelism paramater.

• go to Jenkins -> Manage Jenkins -> Manage Nodes
• check whether all nodes are active and healthy
• Check whether disk space is available in nodes

If everything is fine and if the machine have enough hardware configuration, you can increase the number of executors.
