I noticed that the atlassian-jira.log has grown to 3GB in size. I read the following kb: How to change the size that JIRA rotate the application's log file https://confluence.atlassian.com/jirakb/how-to-change-the-size-that-jira-rotate-the-application-s-logs-files-956698924.html and my file has the default setting already. Is there a way to shrink the file or force it to rotate without having to restart the entire JIRA application. This is on Window server 2016, using IIS 10 and the reverse proxy
