After a few hours running with InfluxDB configured, CloudStack hangs due to OutOfMemoryException raised. The exception happens at com.cloud.server.StatsCollector.writeBatches(StatsCollector.java:1510):
2020-08-12 21:19:00,972 ERROR [c.c.s.StatsCollector] (StatsCollector-6:ctx-0a4cfe6a) (logid:03a7ba48) Error trying to retrieve host stats

Context on InfluxDB Batch: Enabling batch on InfluxDB is great and speeds writing but it requires caution to avoid Zombie threads.
Solution: This happens because the batching feature creates an internal thread pool that needs to be shut down explicitly; therefore, it is important to add: influxDB.close().

Debian-based users/developers can no longer build CloudStack 4.11+
