I read many articles but I didn't find a solution for my problem.
Our SP 2019 on-prem farm consists of: 2x Application with Search, 2x Front-end with Distributed Cache. Each server have 32GB RAM and 8 virtual processors.
Full crawl showed me the following errors:
Error voices like "Processing this item failed" should be related to a high load CPU/RAM. RAM is still < 80%. I have set Performancelevel for search service: PartlyReduced. I increased the timeout value under Farm Search Administration to 600 from 60. Content source contains only one web application. Full Crawl takes more than 5 hours for this content source.
- How do I get rid of these "Processing ..." error voices? (The possibility would be to add another Application with Search server?)
- "SharePoint returned an empty response" - There are files with a size of 0KB. Is it possible to add a crawl rule to exclude?
- "The object was not found" - After loading the url at which this error message is displayed, I get: Page Not Found. Index Reset doesn't work on this problem.
I will be grateful if you help me solve these problems.
