Feature Discussion

Currently, I have the following configuration:

scan-max-active: 200
scan-max-done: 100
scan-max-udf-transactions: 200
scan-threads: 16

Processes terminates If i increase scan-max-active > 200. What else should I do to support this ?

What is printed in the logs when the process terminates?
