I'm still experimenting with this. I had been crawling with a depth of 1 because I don't need anything outside my URLs list, but I tried with a depth of 10. It went through a crawl loop that ended after 3 hours, then a second 3 hour crawl loop, then a third shorter loop. It still stopped 5 URLs short of crawling every URL in my list, though it crawled a few I hadn't included.
Are these 3 hour loops standard for large crawls? -----Original Message----- From: Chip Calhoun [mailto:ccalh...@aip.org] Sent: Tuesday, April 17, 2018 3:27 PM To: user@nutch.apache.org Subject: RE: Nutch fetching times out at 3 hours, not sure why. I'm on 1.12, and mine also defaulted at -1. It does not fail at the same URL, or even at the same point in a URL's fetcher loop; it really seems to be time based. -----Original Message----- From: Sadiki Latty [mailto:sla...@uottawa.ca] Sent: Tuesday, April 17, 2018 1:43 PM To: user@nutch.apache.org Subject: RE: Nutch fetching times out at 3 hours, not sure why. Which version are you running? That value is defaulted to -1 in my current version (1.14) so shouldn't be something you should have needed to change. My crawls, by default, go for as much as even 12 hours with little to no tweaking necessary from the nutch-default. Something else is causing it. Is it always the same URL that it fails at? -----Original Message----- From: Chip Calhoun [mailto:ccalh...@aip.org] Sent: April-17-18 10:45 AM To: user@nutch.apache.org Subject: Nutch fetching times out at 3 hours, not sure why. I crawl a list of roughly 2600 URLs all on my local server, and I'm only crawling around 1000 of them. The fetcher quits after exactly 3 hours (give or take a few milliseconds) with this message in the log: 2018-04-13 15:50:48,885 INFO fetcher.FetchItemQueues - * queue: https://history.aip.org >> dropping! I've seen that 3 hours is the default in some Nutch installations, but I've got my fetcher.timelimit.mins set to -1. I'm sure I'm missing something obvious. Any thoughts would be greatly appreciated.
