It looks like the udplog module version you are using is way too 
old and doesn't contain this 2 years old fix for and API change 
in nginx 0.8.32:

https://github.com/vkholodkov/nginx-udplog-module/commit/e7b8145b96ae9f5be94f0ab0008a8c59cd13c7b8

You may want to get more recent one from Valery's github.
