Solr - facet.pivot.mincount=0 crashes server

I am using Solr 7.3.0 (with pySolr) to search products in my database, returning products, facets and facet.pivots:

result = solr.search(query_s, **{
    'rows': '24', 
    'sort': formatted_sort, 
    'facet': 'on', 
    'facet.limit': '-1', 
    'facet.mincount': '1', 
    'facet.field': ['gender', 'material'],
    'facet.pivot': 'brand,series', 
    'fq': '-in_stock: 77'
})

The query_s selects specific fields, for example: brand:Target AND gender:Men's.

When I add 'facet.pivot.mincount': '0' to the query, my Solr server crashes.

I have confirmed this behavior using a URL, so it isn't a pySolr issue.

What could be the cause for this strange behaviour?

Edit

I am using single cluster mode (not Solr Cloud).

This is a known issue and there is a issue open for this. check here https://issues.apache.org/jira/browse/SOLR-6329

also seems like using minCount=0 processes excessive docs unneccessarily and uses too much memory which might explain crashing the nodes.

Check this jira https://issues.apache.org/jira/browse/SOLR-11711
