Key: NUTCH-117
URL: http://issues.apache.org/jira/browse/NUTCH-117
Project: Nutch
Type: Bug
Versions: 0.7.1, 0.7, 0.6
Environment: Window 2000 P4 1.70GHz 512MB RAM

Reporter: Stephen Cross
Priority: Critical
I started a crawl using the command line using nutch 0.7.1.
nutch-daemon.sh start crawl urls.txt -dir oct18 -threads 4 -depth 20
After crawling for over 15 hours the crawl crached with the following exception:
051019 050543 status: segment 20051019050438, 30 pages, 0 errors, 1589818

This was on the 14th segement from the requested depth of 20. Doing a quick
Google on the exception brings up a few previous posts with the same error but
no definitive answer, seems to have been occuring since nutch 0.6.
