Gary Tully created AMQ-7084:
-------------------------------
Summary: Kahadb pagefile, allocated and unused pages from read
only transactions are leaked
Key: AMQ-7084
URL: https://issues.apache.org/jira/browse/AMQ-7084
Project: ActiveMQ
Issue Type: Bug
Components: KahaDB
Affects Versions: 5.15.0
Reporter: Gary Tully
Assignee: Gary Tully
Fix For: 5.16.0
The work in AMQ-7080 to checkpoint the free list has identified a case where
the free list is not updated to reflect the disk state of an allocated free
page. This can lead to a free page leak in error. In practice this pattern of
usage is not widely used, but it is relevant when the free page list is being
tracked and failure can be arbitrary. It is important that an accurate
reflection of the current state is being checkpointed.
