Error: 2814 - Node shutdown (2 replies)

I am getting the above error with the explanation:

System reports no more file system resources(Internal error, programming error or missing error message, please report a bug). Temporary error, restart node

The setup is 32-bit Windows 7, 4GB RAM.
When the data node is running, task manager shows it using about 1.9GB RAM, in total 84% of the PC's RAM is being utilised (by all running processes).

The node had been running for a few days before it shut down.
(Unfortunately the other node also shut down, same error, both over the weekend!)

This is my config.ini...

[ndbd default]
