Subject [jira] [Created] (VFS-512) LRUFilesCache grows arbitrarly
Date Thu, 06 Feb 2014 11:18:14 GMT
Bela Hullar created VFS-512:

             Summary: LRUFilesCache grows arbitrarly
                 Key: VFS-512
             Project: Commons VFS
          Issue Type: Bug
    Affects Versions: 2.0
            Reporter: Bela Hullar

We are experiencing memory issues in our system where we have to scan very big directories.
After doing some investigation it turned out that the cause of the issue is the caching of
vfs. (

>From this reason we tried out LRUFilesCache, but it seems this cache can still grow way
beyond the limit. 
This can be reproduced with a simple test code:

In this example we set the max size of lru to 100, but running a while this example and then
checking the heap of the program showed that the real size of the map can be 10 000 or more
too. And it seems its growing constantly.
