Hi Solr Users, Solr 9.1.1 version, upon restarting solr on any node in the cluster, a unique event is triggered across all the *other* nodes in the cluster that has an impact similar to restarting solr on all the other nodes in the cluster. There is dip in the cpu usage, all the caches are emptied and warmed up, there are disk reads/writes on all the other nodes.
The nodes in the cluster are usually at 40% cpu usage and 80% memory, they receive certain requests and updates, and at any time solr on a node is restarted, the shards on that nodes take 1-2 minutes to recover and by the time it is recovered, the other nodes receive an event that cause restart like impact on them, seeing caches cleanup, cpu dip and so on. What can cause this type of behavior? Thank you, Rajani
