In some rare cases, if a document is 'assembled', it can stall, giving little or no response to the client.


Requests for that document results in client timeouts.


This might occur when the original document is smaller than the small object cache size limit, but grows to be larger than the small object cache size limit during assembly. In rare cases, this can cause the document to be unservable.


Create a policy node for that specific document, and set to 'proxy always.'

Fix Information

This release corrects a miscalculation, allowing an 'assembled' document to be correctly written to the metastor cache and served to the requesting client.
