There was a major oversight when +TTL nodes were implemented. The session ID generator for each server +is seeded with the configured Server ID in the high byte. TTL Nodes +were using the highest bit to denote a TTL node when used in the +ephemeral owner. This meant that Server IDs > 127 that created +ephemeral nodes would have those nodes always considered TTL nodes +(with the TTL being essentially a random number). + +<a href='https://issues.apache.org/jira/browse/ZOOKEEPER-2901'>ZOOKEEPER-2901</a> +fixes the issue. By default TTL is disabled and must now be enabled in +zoo.cfg. When TTL Nodes are enabled, the max Server ID changes from +255 to 254. See the documentation for TTL in the administrator guide +(or the referenced JIRAs) for more details. + +<p> + +<h2> Sub-task +</h2> +<ul> +<li>[<a href='https://issues.apache.org/jira/browse/ZOOKEEPER-2754'>ZOOKEEPER-2754</a>] -
