Troubleshooting
Problem
Watson Explorer Engine's search API call may hang and return no response. It depends on the contents of documents you crawled.
The issue was reported in the following condition (It may occur in other condition depending on the crawled data).
- Data source is web crawler, and
- In the admin's collection page, "snippet" is appended to the field list of "Output" (Configuration tab> Searching sub tab > Contents section)
Symptom
If the problem happens, the following symptoms can be seen.
- The engine-cmd command or a REST API call with the velocity CGI hangs and never returns any response. High CPU usage (almost 100%) of the velocity process can be observed during the hang-up.
- Application Builder's
rich previewdoes not work. The spinner icon keeps spinning and does not show the preview result.
