We have done an in place upgrade of a SOLR 7.7.2 cluster to SOLR 8.11.1. using openJDK 8.
The core loads fine and searches work as expected. Adding or modifying content causes the leader node to crash with OOM error. No additional errors in the SOLR logs. The writes work and the changes are available in the other nodes. This is a large core (>1Tb). Has anyone seen this issue before? Possible issue with SOLR attempting to reload a cache with too much info? Thanks for time, Paul
