    • Environment:

      Description

      When using the Cache filter it seems that MaxScale crashes on certain events, especially when changes in the database are made (INSERT, UPDATE, DELETE). For example our web application responds with a 500 error, when adding a forum post.

      Might be related to MXS-3694, but regardless of the settings of the cache MaxScale crashes and restarts.
