Bela Ban updated JBCACHE-96:
----------------------------
Attachment: FileCacheLoader.java
> Memory leak in FileCacheLoader
> ------------------------------
>
> Key: JBCACHE-96
> URL: http://jira.jboss.com/jira/browse/JBCACHE-96
> Project: JBoss Cache
> Type: Bug
> Reporter: Bela Ban
> Assignee: Bela Ban
> Fix For: 1.2.1
> Attachments: FileCacheLoader.java
>
>
> There is a memory leak probably caused by a growing HashMap in
> FileCacheLoader (and possibly other loaders). Please refer to the attached
> file, fetched from cvs head as of February 21. The memory leaked is
> proportional to the number of objects put into the cache and their sizes.
> This is true for the cache version 1.1.1 and 1.2 when run inside JBoss 3.2.1,
> I haven't had the time to test it on version 4.
>
> The problem seems to be that the HashMap does not get cleaned up when
> committing a transaction. The cleanup only happens on rollback in the
> standard code.
>
> With the modification in line 198 the leak is sealed, but please note that I
> have no experience with the JBoss-cache source whatsoever, and no tests have
> been made apart from determining that the leak is gone. Tests have only been
> made with the cache configured to be local.
>
> Best regards
> Tom Bakken
