[teiid-issues] [JBoss JIRA] (TEIID-5830) "reload" command increases # of buffermanger instances

[Steven Hawkins (Jira)]

Steven Hawkins resolved TEIID-5830.
-----------------------------------
    Resolution: Out of Date


This was resolved by TEIID-5025 - when the buffermanager shuts down it will cancel it's timer task as well ensuring that no one holds a reference. 

On 6.4 / 8.12.x it's still possible that the weak reference held by the timer task to the buffermanager isn't cleaned up until some time later - but the shutdown method will have been called which mean that the resources held by the buffermanager should already be cleared.
