Portmap translation creation failed

[nstefi1]

Hi all,
Can somebody explain me how to troubleshoot this error in my Cisco ASA 5510 device?
I receive this error regularly (every 10 minutes I receive a batch of 9 messages in a row, around 1 message per second 9 times):

portmap translation creation failed for udp src inside:192.168.0.12/137 dst inside:192.168.15.1/137

I read bits and pieces in other posts about similar errors, but having answers for their very specific configuration, which was a bit difficult for me to understand.

The strange thing is that I cannot find the address 192.168.15.1 anywhere in my configuration and is not supposed to part of my network. I don't have any VLAN having 192.168.15.0 address.
Does this mean that my configuration is bad?

Thanks

In general it means a nat problem. Can you post your scrubbed config? (delete passwords and mask the middle 2 octets of the public ip/s)
