# Wordfence Database Mess

 * I run a large deployment of WordPress and wordfence for a webhosting company.
   The wordfence plugin causes a mess in our customer databases. We constantly see
   an issue for tablespace issues for these specific tables.
 * IE.
    [ERROR] InnoDB: Could not find a valid tablespace file for ‘”databse”/pom_wfNet404s’.

    wfHoover wfNet404s wfVulnScanners
 * Can you shed any light on why these tables are constantly corrupted and causing
   an issue?

 * I have just post about a similar issue, this is so bad that I have to manually
   go into each one of our client sites, disable wordfence with the option to remove
   its tables, just to be able to backup our users.
 * This is not a new issue either.

 * We have that similar issue with the backups. Some of these tables also corrupt
   the ibdata files so bad the instance crashes and we either have to rebuild from
   a backup or take a mysqldump of each database and table separately.
 * Removing these table seems to help, but is a bogus solution as the customers 
   usually re-install them shortly after

 * My only option right now is to not use wordfence on any of my client sites. the
   problem is even removing the tables is alot of work as the flag has to be set
   manually on every site then deactivated to remove these tables properly, unhappy
   situation to say the least.

 * Hi [@obsete](https://wordpress.org/support/users/obsete/),
 * In case there is low disk space, that can definitely happen somewhat regularly.
 * Also, could you please confirm which version of MySQL you’re running?

 * Hey Wrfyann,
 * In this case low disk space is not an issue. These issues we also see across 
   all of our customer databases (about 100 servers).
 * We currently run percona 5.6.37

 * Hi [@obsete](https://wordpress.org/support/users/obsete/),
 * Sorry about the delayed response.
 * We do get reports of Wordfence tables crashing every now and then, but it’s not
   something we see consistently.
 * I’m not sure about the specificity of _Percona Server for MySQL_ and it’s not
   a MySQL _flavor_ explicitly [supported by Wordfence](https://docs.wordfence.com/en/Wordfence_system_requirements#Database).
 * What I suggest at this stage is that you reach out to Percona and ask if they’ve
   seen similar issues and if so, how they solved them.
