Robert,

What is at the end of solr.log when it has died?

Is there anything in syslog or messages?

What is the other app?

Run the top command, memory screen, on Ubuntu:

$ top -o RES

I have never used strace(1) on Solr, but that is an option. Run Solr in 
strace with the appropriate options to reduce the voluminous output.

You could upgrade your hardware cheaply at a surplus store (almost every 
machine in my office is surplus .. think .. actually, every one).

cheers -- Rick
