I have been thrilled with using this product on a large e-comm site with 200K products.
However, I have had a problem with the Crawler Limitations > Maximum Execution Time > Set for 18,000 Sec (5 hours). It continues to run regardless of my setting.
Also, I would like to run as a cron job over several days in 5-6 hour increments, but I can't get the program to pick up where it left off on the last run. It simply overwrites the previous partial crawl unless I run the process manually. In other words, I can't keep checked the Crawling > Resume Last Session > Continue the interrupted session.
Running Unlimited v5 on php 5.2.17.
If needed I can provide credentials for access (via PM).
