Deleted tag shows warnings in log

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.

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.
