How to stop Jenkins log from becoming huge?

Question

Recently my jenkins.log has started getting very large, very quickly, full of exceptions about DNS resolution. I attempted to use logrotate, but the log file grows too quick

Answer 1

In my case I received the log entry whenever a Sign in attempt was rejected via the user interface.

User authentication is done via LDAP and the provided user/password tuple is correct. After a while the sign in attempt is working.

Is it possible that the user is rejected because of the enabled DNS Multi cast feature?
