Hello, we are currently working on a tool that uses dbpedia to gather the rdfs:label(s) behind certain urls. We use nodejs to query at http://dbpedia.org/sparql. Everything works brilliant for about a few hundred requests. At a certain point all we get back in response is the following: 'status: 500 response: Virtuoso 22026 Error SR477: Error serializing the value into an ANY column'. We fire about one request every 1-2 seconds. Because we could not reproduce the error other than waiting a unspecific amount of time/requests, before every requests responds with the above mentioned error, my question is whether there are any stricter limits of requests per second or hour, or if the error is the result of something different. It might be of interest that the same error occurs on the web interface as well, if it was triggered via the nodejs requests before.
