Matthew Caruana Galizia commented on SOLR-10937:
------------------------------------------------
Thank you for that suggestion. Before I post, perhaps you could let me know
what you think based on the following:
- the size of the index is 375 GB
- there are 10,824,670 documents
- there's 612 GB free on the Solr data partition
- the index is fully optimised (segment count is 1)
The error happens every time the core is loaded. For example, when Solr is
restarted or I press the Reload button the Core Admin section on the Solr UI.
