Hi Mika,

I've just run some tests depositing 100 items in a row from the PHP library, 
and it seemed to work fine. Indeed, with an earlier version of DSpace we 
deposited 1/3rd million items into DSpace, with 4 concurrent threads (using a 
custom Java SWORD load test tool) and it worked fine.

This page has a good description of PermGen, and a JSP page that allows you to 
watch the memory usage. What container and version are you using?

Hi Stuart,

Actually I've been using Sword PHP library and it seems great. The
only thing I've noticed, is that if I run, say 10 deposits in a row,
my servlet container hangs and Java gives me the following memory
error. Now this makes me wonder if there's some leakage somewhere in
DSpace SWORD implementation or in PHP SWord library?

HTTP ERROR: 500
PermGen space
RequestURI=/neuroportti/handle/0/23
Caused by:
java.lang.OutOfMemoryError: PermGen space

Any ideas what might be causing this?

Thanks,
Mika
