Cannot allocate memory error

Question

Hello,
I am using:
Oracle: Berkeley DB XML 2.5.16: (December 22, 2009)
Berkeley DB 4.8.26: (December 18, 2009)
When attempting to open a container in an environment where the application process has been running for a while I get the following error:
XmlDatabaseError: XmlDatabaseError 12, Error: Cannot allocate memory
The Python bindings do not have support for errcall. I have added errcall support to the bindings but I do not appear to be receiving any message (but it is new code so I do not trust it completely).
Running the dbxml shell tool I get:
[root@localhost db]# dbxml
Joined existing environment
dbxml> open test.dbxml
stdin:1: openContainer failed, Error: Cannot allocate memory
dbxml>I don't appear to be out of locks:
