---------------------------------
Summary: Solr replica remaining down status when hitting the
maxQueueSize as 20000
Key: SOLR-13061

Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: SolrCloud
Affects Versions: 7.2.1
Environment: Cluster info: 6 nodes, 30 Solr servers
1000 collections, 10 shards per collection, 3 replica per shard
Exception happened when restarting Solr cluster.
Reporter: Zhaohui Ma
1. Cluster info: 6 nodes, 30 Solr servers
1000 collections, 10 shards per collection, 3 replica per shard
Exception happened when restarting Solr cluster.
2. Exception happened when restarting Solr cluster. The question is NO
exception hander is defined when this exception
"java.lang.IllegalStateException: queue is full" is thrown when arriving at the
threshold
STATE_UPDATE_MAX_QUEUE 20000 defined in Overseer. And the core fails to
preRegister and never come up again.
3. Suggestions:
a. Is this configuration STATE_UPDATE_MAX_QUEUE reasonable?
b. IllegalStateException should be handled and retry logic should be added.
4. Detailed error is given as below.
