Hello Siemens forum community,

I am facing an issue with high CPU usage and memory consumption by the SIMATIC WinCC CCProjectMgr process on my HMI Server. I hope you can provide some guidance and insights into this matter.

The problem I'm experiencing is that the SIMATIC WinCC CCProjectMgr process is consuming a significant amount of CPU resources and memory on the HMI Server. Surprisingly, I have only three clients connected to the server, which makes this behavior quite unexpected.

These high resource usage levels are causing system slowdowns and affecting the performance of the HMI interface.

I have already performed some initial troubleshooting steps, such as checking for error logs and reviewing system resource usage. However, I haven't been able to pinpoint the exact cause of this problem.

Therefore, I kindly request your assistance in understanding the possible reasons behind the high CPU usage and memory consumption by the CCProjectMgr process. Are there any known issues or recommendations for optimizing its performance?

Any advice, insights, or suggestions you can provide would be greatly appreciated. If there are specific diagnostic tools or logs that I should investigate, please let me know. I am willing to provide any additional information that might be helpful in resolving this issue.

Thank you in advance for your support and expertise. I look forward to your valuable input and assistance in resolving this matter.

Best regards,
Gali
