                 Key: SOLR-15998
                 URL: https://issues.apache.org/jira/browse/SOLR-15998
             Project: Solr
          Issue Type: Test
      Security Level: Public (Default Security Level. Issues are Public)

    Affects Versions: 8.4.1
            Reporter: Mark


Hello,

This is my Solr Cloud cluster.

 

16 Shard 
    1 LEADER   (replicaType=TLOG)
    1 REPLICA  (replicaType=TLOG)

Node Information
    4core vCPU
    32 GB Pysical Memory
    16~20GB SOLR - JAVA HEAP
    500 GB SSD

Traffic
    - Write 10,000 ~ 30,000 document/Per sec  

    - Solr Index Size - using 50% disk 


In this situation, all replicas are down when performing Select Query. (Oom killer event occurs)


However, this does not happen in case of replicaType=NRT.


NRT write performance is severely degraded, so we try not to use it.
