We had a case where we were trying to execute a script to delete 3000 records from a table. Each delete would create 2 sql statements due some customization.

When we ran the test report, we first received a message that asked us if we want to wait because it was taken a long time. After clicking wait, eventually the website returned automatically to the main dashboard.

When we checked the log of the test run we noticed that we didnt have a complete message. The script stopped while still running. Reason unknown - possible memory issue or a timer? To many records in the log? Who knows, we didnt get an error message.

We asked MS and we received the respons that this workload is not supported in the custom script feature.

We would like to ask to reconsider because certain data fixes might be needed in the production environment. Doing this without a down time is very appreciated.
