Hi Danilo,
you have to give more infos about your system and the config.
- 30gb RAM (physical RAM?) how much heap do you have for JAVA?
- how large (in GByte) are your 40 million raw data being indexed?
- how large is your index (in GByte) with 40 million docs indexed?
- which version of Solr and JAVA?
- do you have JAVA garbage collection logs and if so what are they reporting?
- Any FullGC in GC logs?
Regards, Bernd

Hello all,
We have a configuration with a single node with 30gb of RAM.
We use it to index ~40MLN of documents.
We perform queries with edismax parser that contain often edismax parser
subqueries with the syntax
'_query_:{!edismax mm=X v=$subqueryN}'
Often X == 1.
This solves the "too many boolean clauses" error we got expanding the query
terms (often phrase queries) directly in the main query.
Unfortunately in this scenario solr often crashes while performing a query,
even with a single query and no other source of system load.
Do you have any idea of what's going on here?
Otherwise,
What kind of solr configuration parameters do you think I need to investigate
first?
What kind of log lines should I search for to understand what's going on?
Thank you
Danilo
