Users are unable to access the OverOps backend caused by DB storage running out of disk due to MySQL binary log files.
OverOps Backend: all versions
MySQL DB server: 5.5, 5.6 or 5.7
Purge the MySQL binary log files from the DB storage.
For details see https://www.cyberciti.biz/faq/what-is-mysql-binary-log/
To purge on a 100% full disk, one must either add additional space to the full disk or clear a few binary files in order to be able to perform a mass purge.
Binary log files are configured to be backed up or replicated onto the same disk where the database resides. If not purged on a regular basis, these files will take up all the disk space and therefore will make the DB server inaccessible.
