This is a completely different issue. It is due to the way your webfarm is configured. Apparently there is a problem with the syncronization of the different server nodes. Our default implementation on the matter involves the use of our Load Balanced module and is described in our Documentation
Since I cannot see if you have the Load Balanced add on from your account information I can suggest you investigate the same topic regarding the setup your solution uses.
