It looks like you have written a lot of correction values in a short period of time.
Do you know which actions have been started when the log messages have been written?
Was the log message wirtten during runtime or at startup of the project?

Which WinCC OA version are you using?

Yes, you right, we write a lot of correction values, but how much values we can written without this errors? Which limit for changing correction values?

[m.sabitov]

We found a little bug B) in our script and fix this errors.
Thanks for help.

I don't know a defined limit for the number of correction values which can be written in a given period of time.
How much values can be written and processed depends on several factors:
-- configuration of the archive
-- value changes / second during normal operation
-- used hardware (HD/SSD)
...
