Dear Fuseki users, I want to use Fuseki 2 for querying various big ontologies, e.g. dbpedia. However, I have encountered the problem that Fuseki is ignoring the timeout setting.
I started the server with ./fuseki-server --timeout=100000 which should set the timeout to 100s, but it is rather 3s (see below). I have seen that there were some discussions regarding the handling of timeouts, but I'm not sure if this is related to my problem. Here's the log - please note that I'm using one of the latest snapshot builds (the official 2.0.0 release is behaving the same way for me): [2015-04-17 09:53:14] Server INFO Fuseki 2.0.1-SNAPSHOT 2015-04-16T16:45:46+0000 ... [2015-04-17 09:53:58] Config INFO Register: /dbpedia_topical_concepts_unredirected_en [2015-04-17 09:53:58] Config INFO Register: /dbpedia_wikipedia_links_en [2015-04-17 09:53:58] Server INFO Started 2015/04/17 09:53:58 MESZ on port 3030 [2015-04-17 09:54:12] Fuseki INFO [1] POST http://xxx.xxx.xxx.xxx:3030/dbpedia_page_links_unredirected_en/query [2015-04-17 09:54:12] Fuseki INFO [1] POST /dbpedia_page_links_unredirected_en :: 'query' :: [application/x-www-form-urlencoded charset=UTF-8] ? [2015-04-17 09:54:12] Fuseki INFO [1] Query = select (count(*) as ?count) {?s ?p ?o} [2015-04-17 09:54:15] Fuseki INFO [1] 503 The query timed out (restricted to 100000 ms) (3,098 s) The problem appears with other queries as well. Sometimes limiting the result set (e.g. by appending "LIMIT 20" to the SPARQL query) helps. The system is a quad core virtual machine with 32 GB RAM, running Ubuntu 14.04. "java -version" is reporting: OpenJDK Runtime Environment (IcedTea 2.5.4) (7u75-2.5.4-1~trusty1) OpenJDK 64-Bit Server VM (build 24.75-b04, mixed mode) I would highly appreciate any advice. I really like Fuseki and would love to use it for some data mining in medical informatics.
