[elephant-devel] Berkeley DB error: Cannot allocate memory.

[Ian Eslick]

Well, based on the stat output it appears that you don't have any  
resource issues so something else must be going on.

Can you break this down to a test case?   Also, have you tried running  
this with elephant-unstable?

Thanks,
Ian
