Web Interface Crashes When Using Renderer (search) while Crawling

[jbondhus]

As stated. When a crawl is running, if a search via the renderer search field is attempted, the web interface locks up completely. Attempts to load the web interface fail, with the browser waiting indefinitely for a response from the server. I have to do a reboot from my VM management console as the opensearchserver service refuses to restart properly. This means that crawls must all be stopped in order to do a search. SSH works, and memory usage is normal, with CPU usage is around 1%. See the below screenshots and log files for more information.

Renderer:

• General
• Fields
• Search Dialog

Crawler:

• Crawl Process

Runtime:

• Cache
• Index
• System
• Advanced
• Threads

Logs:

• oss.log
• server.out

An update - the crawl process configuration is the source of the problem. If auto-complete is enabled to be rebuilt after indexing, the server will crash when a search is performed. This appears to happen whether or not the auto-complete item exists in the configuration (I tried with and without it)

Thanks for the details.

These two exceptions should be better handled. They seems to be the reason of the crash. We work on that.
