Hello Cristian,
The possible reasons for this error are described here: http://adwordsapi.blogspot.com/2011/03/concurrency-management-in-adwords-api.html In your particular case I recommend removing multi-threading and using MutateJobService<http://code.google.com/apis/adwords/docs/reference/latest/MutateJobService.html>instead. This service automatically retries on errors like this and also you will use much less API units. The change should be easy as the service receives the same operation structure as the AdGroupCriterionService. -Danial, AdWords API Team.
