out of memory error with TestDiskCache




Hi,

I am new with JCS, so pls forgive my ignorent.

set up.
downloaded jcs-1.0.jar and three commons.xxx.jar and junit.jar;
copied TestDiskCache.java from
http://jakarta.apache.org/turbine/jcs/xref-test/index.html(only mod is
package).
copied a config file. contents below

test
run test. a success.
modified number of items to 200000, out of memory.

Could someone tell me what is the problem? 200000 keys won't consume that
much memory, would them?

Thanks.

shaohua

config file ( I tried with different maxobjects attr and no help)

There cache isn't made to just dump items into it as fast as possible. 

Hmmn

Re: out of memory error with TestDiskCache

Posted by Daniel Rosenbaum <dr...@yahoo.com>.
Shaohua,

I have a feeling this is the same problem discussed in the
recent thread "Memory test".  Look there for my comments about
cache events not firing quickly enough to keep up with the loop,
so the items are not being removed from the purgatory quickly
enough either.  This is causing memory to run out before the
loop ends.
