Hi all!

Can anybody, please explain me why I get "The AXIS engine could not
find a target service to invoke! targetService is
ExternalKeywordResearchServiceV5" exception regularly, when trying to
obtain related keywords through KeywordResearchService.getRelatedKeywords
(v.5.0.0)?

I am using several threads with same credentials to increase
performance. Each thread uses same credentials but queries for related
keywords for different source keywords.Can you please explain me what
does this exception mean? Maybe I should decrease a number of parallel
threads or something?

Regardless using parallel threads, sometimes, I receive this exception
even if I call this single method.

Thank everybody in advance.
