---------------------------------------
Summary: Investigate Potential Memory Leak in HeavyQueriesTracker
(Apache Ignite 2.17.0)
Key: IGNITE-25449
URL: https://issues.apache.org/jira/browse/IGNITE-25449
Project: Ignite
Issue Type: Task
Affects Versions: 2.17
Reporter: Oleg Valuyskiy
Assignee: Oleg Valuyskiy
Following the upgrade from Apache Ignite 2.16.0 to 2.17.0, a significant
increase in JVM heap memory consumption was observed, with ~80% (600MB)
attributed to {{{}HeavyQueriesTracker{}}}'s {{{}ConcurrentHashMap{}}}. Analysis
suggests suspended {{TrackableQuery}} instances are never removed, causing
unbounded map growth.
