Repetitive error in log

[Yay N' Stuff]

Hi all,

Maybe someone can shed some light on these errors that are making my log files enormous (900MB a day), i logged intoday and discovered 77GB of logs with this:

https://pastebin.com/JwyZBs3n

It seems to be in a different log to the main jira log eg: localhost.2019-02-02.log

They are all 'localhost' <then some date>

Jira passes all its health and integrity checks when I check from the web interface.

any clues where to start hunting?

Edit: Jira version is v6.4.14

Seems to have been bot activity related... Soon as i banned the bots (ahrefsbot, semrushbot), that log is now silent.

Would be interesting to know what they could have been hitting to trigger so much logging.
