我已经设置了一个本地Dbpedia镜像 - 个人查询工作正常，但是当我尝试更多查询时，我从Virtuoso收到以下错误：< / p>
17:45:46 WARNING: * Monitor: System is under high load. Adding cluster nodes or using more replicated copies may needed
17:47:03 WARNING: * Monitor: Locks are held for a long time
17:47:40 WARNING: * Monitor: No Web Server threads avalable, ServerThreads in [HTTP Server] may have to be increased
有关如何解决此问题的任何想法？我已经增加了ServerThreads中的virtuoso.ini。
