Randomly I now seem to get this error in production where it was working fine for more than a year....
java.lang.NullPointerException > at > org.apache.nutch.searcher.FetchedSegments.getSummary(FetchedSegments.java:248) > at > org.apache.nutch.searcher.FetchedSegments$SummaryTask.call(FetchedSegments.java:63) > at > org.apache.nutch.searcher.FetchedSegments$SummaryTask.call(FetchedSegments.java:53) > at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) > at java.util.concurrent.FutureTask.run(FutureTask.java:166) > at > java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) > at > java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) > at java.lang.Thread.run(Thread.java:636) > + for some queries, the first hit pages are fine and suddently it stops and I get a blank page, for some I get it on the query + I checked the query with Luke. Looked fine + the preceding bean call in search.jsp (bean.search(query, start + hitsToRetrieve, hitsPerSite, "site", sort, reverse); did not generate any exception as far as I can judge. What can be the cause of that ? how to debug that one ? I'm using Nutch1.0. -- -MilleBii-
