So for the past couple of days, without any known configuration changes or server changes, I've been getting massive error_logs with lines like the following making up for most of the files. To the tune of about 100,000 lines/second. These logs keep filling up my server's disk space every six or so hour, going up to about 40G in six hours. What does this error mean? How can I fix it or find the root cause? Let me know if you need any more information.
