UiPath Version:
2024.10.16
Problem:
On Windows Server 2022 machines running UiPath (v2024.10.16), memory usage keeps increasing over time.
The high consumption is linked to the User Profile Service, eventually impacting system stability.
Solution:
After multiple sessions with UiPath Support, the root cause could not be directly attributed to the UiPath Robot itself.
We tried several mitigations beforehand, including:
-Applying system environment variables related to behavior and sessions
-Adjusting robot settings in Orchestrator
-Upgrading the Robot version
None of these steps resolved the issue.
Further investigation showed that the problem is indirectly triggered by UiPath: the frequent logon sessions created by the robot cause User Profile Service memory usage to continuously increase. When the robot logs off, the memory is not released, due to a known issue in Windows Server 2022.
Solution:
Updating the Windows Server 2022 OS to a newer build fixed the underlying OS issue (registry handling and memory cleanup). After applying the OS update, memory usage stabilized and the problem was resolved.
Recommendation:
If you encounter high memory usage related to User Profile Service on WS2022 with UiPath, make sure the operating system is fully updated.
