Hello, We are having problema
We have a cluster with Solr 8 (15 nodes running RHEL) and ZooKeeper 3.6.2 (5 nodes) and only one collection of around 48 millions of docs with 10 shards and a replication factor of 3, so every server holds 2 cores. A couple of weeks ago we performed an upgrade from Solr 8.9.0 to 8.11.1 and we upgraded the Java version too from 1.8.0_322 to 11.0.14 and since then some cores are constantly growing even when the number of docs is practically the same. I have upload an image where you can see how the size of a core grows over time (we upgraded on 05/02), and another graphic where you can see the docs number is quite stable compared to their size: https://we.tl/t-pvV4RfXhYe Currently the size of that replica of shard2 is 22,6 GB while leader shard is 9,66 GB We don't have any custom merge policy in solr.config file, we are using the default merge policy. When we restart an instance with a core that grows indefinitely it release space. For ex, I have restarted the instance which graphic I shared and now its size is 9,9 GB. But after a while (some days) some cores grow again. I have upload a COLSTATUS too with information about shard leaders and their segments. Any ideas about this issue? Thanks!
