Description
NOTE: This suggestion is for Confluence Cloud. Using Confluence Server? See the corresponding suggestion.
Confluence captures useless exceptions in the logs when a htttp client aborts a download. Client abort is a very common event and should not be logged because there is nothing the server or server administrator can do about it. We have hundreds or thousands of exceptions like this in our logs per day which we'd rather not see.
It's very common for crawlers to abort large downloads while crawling a site, which I assume is the biggest contributor to the number of these exceptions that we see.
