barbalex commented on issue #1088: cpu usage 100% caused by silence and fs-manager URL: https://github.com/apache/couchdb/issues/1088#issuecomment-355323789 @garrensmith Yep, you were right. These were crypto miners. I found a mailing list mail from Sinan Gabel explaining how to turn off the miner. Unfortunately I do not know how to link to Sinan's mail so here is the gist: I needed to remove a cron job created from user couchdb: ``` sudo -i su couchdb crontab -e // Then remove the line in the cron // save and reboot ``` So thanks a lot to you and Sinan Gabel. Of course I will also have to rebuild my servers now. My biggest concern now is: How to prevent this from happening again, as these couch instances were not in admin mode.
