In my instance I could insert or update record with a batch size of 100 records without problem.
The last week and with the same code in production we started to get the apex cpu limit and we have to reduce the batch size to 10!!
Even the test classes in production started to fail. The same classes that worked perfect days before. How is this possible??
I think it's very strange. Salesforce does not give any explication and only send information about this limit. I know why this limit occurs but dont understand that, one day works fine and suddenly everything start to fail...
Anyone had had something similar?
