The instance column in the build_requests table in the nova_api db has the type TEXT, which is 65535 chars in Mariadb. The length of the blob that is in the nova api logs is around 67000 chars. This makes the db insert fail. This looks like more of a nova issue than magnum. In the case of Magnum, the workaround is to not include some of the SoftwareConfig files.
