Web Crawl Memory Management
Contributor II
I tried to crawl a fairly large site recently and despite giving my rapid miner process 1024M of heap memory, the app eventually crashed with a memory exception. I was using the Crawl Web component. I think what I probably need to do is store my urls to follow in a database or on a file rather than trying to hold all that in memory. Does the Process Documents from Web component enable that functionality? It seems like it pretty much has the same link following functionality capability as the Crawl Web component. Can someone confirm?

1024M of memory is not that much - maybe you should increase that value. Furthermore, did you enable "add pages as attributes"? In that case, the contents of the page is kept in memory. For large crawling projects that can easily consume all your memory, even on large machines. Instead, disable that parameter and use "write pages into files" instead.
Best regards,
