Worker Process With ProcessId Of xxxxx Serving Application Pool UiPath Orchestrator Has Requested A Recycle Because The Worker Process Reached Its Allowed Processing Time Limit

Resolution when a Worker Process with process id of xxxxx serving application pool 'UiPath Orchestrator' has requested a recycle because the Worker Process has reached its allowed processing time limit.

IIS d​​efault value of recycling application pools is 1740 minutes or 29 hrs.

To change it,

  • On Orchestrator Server machine---IIS-->Application pools--->UiPath Orchestrator-->Recycling(Under Edit Application Pool)

Why is Recycling required ?

29 hrs or 1740 minutes is the default value set by IIS for application pools. Refer Recycling Settings For An Application Pool .

Recycling means that the worker process that handles requests for that application pool is terminated and a new one is started. This is generally done to avoid unstable states that can lead to application crashes, hangs, or memory leaks

Resolution: Sometimes, Recycling can interfere with Robots running the Jobs. To avoid this,

  • Choose a time that works best for you. Select a specific time when no jobs are run by the Robots.
