kaivalnp opened a new issue, #14875:
URL: https://github.com/apache/lucene/issues/14875

   ### Description
   
   Opening this to discuss how we could catch issues (early on) with the new 
Faiss vector format (#14178) -- like memory leaks or bugs in Faiss itself, 
under more rigorous scenarios -- perhaps using long-running (or "monster" tests)
   
   This is important because we're dealing with native code, without fine 
control over memory allocation and error handling -- and could result in the 
JVM crashing!
   
   One such example is #14847, where we discovered an issue with attempting to 
index >2GB of vectors in a single field in a single segment (this issue was 
more on the codec side and how we passed data over to Faiss instead of the 
native part, but the above tests would help catch this nonetheless!)
