Bela, I would like to follow up. I notice in FishEye that you changed the log
statement in BaseEvictionAlgorithm.java from warn to debug but as far as I can
tell you did not change it in LRUAlgorithm.java. Did you perhaps forget about
it? I just want to make sure it wasn't missed, as this is
One comment though, could it be made into a debug or info message rather than a
warning? I have my logs configured to show warnings and would rather not see
such log messages at all, since it is not really a problem. I am not sure why
it deserves a level of warn.

Thank you Ben for resolving this.
Cheers,

After working for a while I was able to come up with a JUnit test case that
reproduces this. The code is below. I started with the
org.jboss.cache.eviction.LRUPolicyTest class and added the following test:
public void testForEvictionInternalError() {
| try {
| String rootStr =
One other thought, you say that "the remove method is supposed to remove it
from the eviction queue". When I call remove("/"), are all child elements of
that node also being removed from the eviction queue? And the children's
children at all levels of the subtree? Maybe what is happening is t
Thanks Ben for responding. Unfortunatly it does not happen every time. All I
know is that I have had an application running with JBossCache for about 6
months now and I get messages such as this about once a week or 2, sometimes
more often and sometimes less.
I have a process that runs every
Could one of the "eviction guys" please comment on this issue? Or should I
file a bug report?
Thanks once again,
Daniel

Thanks Bela for responding. But is this the correct way to clear the cache?
Or is there some other proper method or API that I missed (and prefereably
would not result in these error messages)?

I used the following code to remove all the nodes (all parents and children) in
a TreeCache:
TreeCache cache =
| Fqn root = cache.get("/").getFqn();
| cache.remove(root);
However shortly after this I get messages such as the following in the logs:

My system has many different types of data and I need them to expire at various

Unfortunatly I don't have access to JProfiler. However I notice that a new
Object[] array seems to be allocated for each Region defined, so it is not
sufficient to create a test case that allocates only one array. My application
has eviction policies on over 50 different regions. Might this b
Oh yeah, I forgot to mention that I took this heap dump when the app was
initialized right after Hibernate was finished configuring. Nothing was even
placed in the cache yet at this point.

Ben,
Thanks for your reply. The numbers in my profiling here is only the amount of
memory used for the Object[] array with empty slots, I do not think it includes
any objects actually referenced by the array itself. In other words, it is
13600272 bytes just for having an Object[] array of 200
Hi,
I am heap profiling my application that uses JBoss Cache 1.2.4SP1 and am
finding that the eviction seems to be using quite a bit of memory. In
particular, here are snippets of my hprof output:

Hi,
There still has not been a response. Does anyone have a suggestion please how
to clear the entire cache right now? And is it wrong to simply do
cache.remove("/")? If so why is it wrong, will memory not be freed up or
something like that? And why would the eviction class log these as err
Thanks for the answer Ben. In my application, I have certain data that
periodically gets loaded into the database by a different app, a batch load
process. I would like to clear my cache after this load process, so that a new
database load is forced and the new data would be used, rather than
Actually, I traced these errors to consistenly happen after I do the following:

to do, since I get those eviction errors afterward? If it is not, what is the
proper way to clear the conte
Sorry, I posted this in the wrong forum. I'll repost this in the JBossCache
forum.

Hi,
I constantly get exceptions such as this, using JBossCache with Hibernate:

evict(): Node not found with this fqn: //org/ifmc/qies/qw/data/po/QwEnvrmt
