LU allocate xlate failed

[umut.nurkan]

I keep getting the following syslog messages on my ASA5545:

NAT/PAT pool exhausted. Unable to create connection

LU allocate xlate failed

I read some other discussions that this may be a bug, but I want to make sure.

How many nat translations do you see on the firewall? on the Xlate-table?

Are there enough sessions to cause this?

I may have the same issue with my standby ASA.

Cisco Adaptive Security Appliance Software Version 8.6(1)12
Device Manager Version 6.6(1)

I re-arranged my NAT table per Cisco TAC but it didn't solve the issue.

Thanks,
