Hi Simon: While I don't doubt for a moment that there are undiscovered memory leaks in DSpace, I'm not sure I follow the case you describe. By 'object cache' I'm guessing you mean the cache that is held by the Context object. This cache is private to the Context instance, and Contexts as a rule don't live very long (typically a single HTTP request), so I don't see how spidering activity could accumulate objects in it.
There are other cases - like ItemImport or MediaFilter runs - that use a single context instance (therefore cache) and might iterate over the whole repository, and *could* suffer from what you describe, but as of 1.4 at least, these apps were all recoded to flush their caches. Hope this helps, Richard R On Thu, 2008-03-13 at 13:03 +0000, Simon Brown wrote: > Another thing you should consider is removing the object cache.
