Hello, i tested some scripts in expression Tags. This scirpt was in a UDT (many times used) and shows some errors. Now i have many warnings in the gateway logs. I deleted the Tags the warnings are still in the logs. ![2021-12-09 10_43_01-Window](https://us1.discourse-cdn.com/inductiveautomation/original/3X/5/2/52f0bb9b09202234371d4a1619b32143779aebb3.png) After a gateway restart the CPU is at 70%-80% (usually 10%-20%). We started a backup but now we have many warnings in the logs. Anyone have an idea? ---

Seems you are missing a second argument of type number in your expression function script ---

The second argument was there but the error shows in UDT. If i copy and paste the script in the Tag, i had no errors anymore. But now i deleted the Tags and the error is still there.
