Excessive Resource Adapter JCA connection creation and latency during IdleRemover execution in JBoss EAP
Issue
-
When using a JCA resource adapter, the number of active/idle connections increases significantly (e.g., tens of thousands) even if
max-pool-sizeis set to a low value (e.g., 100). This leads to severe response time delays (over 1 minute) when theIdleRemoverthread triggers, as it blocks the pool while processing a massive volume of connection destructions. -
Resource adapter connection pool usage increasing by
min-pool-sizeon each connection request and the max-pool-size does not seem to be applied in JBoss EAP
Environment
