java.io.IOException: Not enough space

Anand pinged me today for an error. The AppsLocalLogin.jsp page would not open up. He showed me the Apache logs :

I checked the output of swap -l
It was not returning anything.
We checked for space on /var and found that it had a 2GB file called swapfile
I immediately added swap -a /var/swapfile .

The issue was resolved.
