python - Scrapy spider stops abruptly -


i using example here. change identity tor/privoxy have faced several issues such having type "scrapy crawl something.py" multiple times start spider or having spider stop abruptly in middle of crawl without sort of error message.

something.py

class it(crawlspider):     name = 'it'      allowed_domains = ["www.jobstreet.com.sg"]     start_urls = [         'https://jobscentral.com.sg/jobs-it',     ]      custom_settings = {                        'tor_renew_identity_enabled': true,                        'tor_items_to_scrape_per_identity': 20                        }      download_delay = 4     handle_httpstatus_list = [301, 302]      rules = (         #rule(sgmllinkextractor(allow=(), restrict_xpaths=('//li[@class="page-item"]/a[@aria-label="next"]',)), callback="self.parse", follow=true),         rule(linkextractor(allow_domains=("jobscentral.com.sg", ), restrict_xpaths=('//li[@class="page-item"]/a[@aria-label="next"]',)), callback='self.parse', follow=true),     )      def parse(self, response):              items = []              self.logger.info("visited outer link %s", response.url)              sel in response.xpath('//h4'):                 item = jobsitems()              next_page = response.xpath('//li[@class="page-item"]/a[@aria-label="next"]/@href').extract_first()              if next_page:                 base_url = get_base_url(response)                 absolute_next_page = urljoin(base_url,next_page)                 yield scrapy.request(absolute_next_page, self.parse, dont_filter=true)      def parse_jobdetails(self, response):          self.logger.info('visited internal link %s', response.url)         print response         item = response.meta['item']         item = self.getjobinformation(item, response)         return item      def getjobinformation(self, item, response):         trans_table = {ord(c): none c in u'\r\n\t\u00a0'}          item['jobnature'] = response.xpath('//job-snapshot/dl/div[1]/dd//text()').extract_first()         return item
