When accessing Logicmachine scada-main, the CPU load sometimes exceeds 100% - Takayuki Miura - 17.09.2024
Hello!
This time, as the title of the thread says, when accessing scada-main, the CPU load exceeds 100%, making it inaccessible for about 4-6 minutes, and when under high load, the event script that you want to run on logicmachine is not executed.
This problem occurs irregularly and does not occur only under certain conditions.
The same problem occurs with both local network and VPN connections.
Product information
HW: LM5 Lite (i.MX6)
SW: 20211215
I have about 10 LMs purchased around the same time, and this problem is particularly noticeable on three of them.
What do you think the cause is?
Could it be due to a hardware malfunction or a firmware bug?
This problem has not occurred with LM5 Lites purchased after June 2023, so we believe that it may be resolved by updating the firmware.
SW:20230612
For example, if I update the firmware from 20211215 to 20230612, please let me know if there are any problems that may occur.
It is difficult to revert to the original version after a problem occurs, so I would like to make a careful decision.
I look forward to your reply.
Best reggards,

How many objects do you have? Use the latest 2024.04 firmware: https://openrb.com/firmwares/

about 400 objects.
I also have about 400-550 objects for the LM with the same firmware, and I would like to know why this problem occurs on only three of them.
I have about 10 LMs with the same firmware, and this problem occurs on three of them.
Also, please let me know if there are any problems that can occur with the firmware update.

In general firmware upgrade is a safe operation. But make a backup before the upgrade just in case.
Excessive load can be caused by a lot of things. You can install the System load app on LM and check which process is causing high CPU load.

Install System load app to see what is the reason for high load.
