ASA 5520 - LU allocate xlate failed - Failover unit reloads

We just had an issue with our failover unit reloading. In perusing the logs there were a number of %ASA-3-210007: LU allocate xlate failed, errors prior to the reload. These units had just had their OS upgraded to fix a DOS issue a few weeks ago. I have not seen the error since it reloaded. However, I was asked to report the issue just in case it is a bug in the new version of the OS.Two units in failover.

I noted a report on errors with verison 7 and a conflict between nat(0) and static commands. I don't show nat(0) being used on these units.
