Subject out of memory error with TestDiskCache
Date Fri, 12 Sep 2003 20:10:29 GMT




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.

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