I am guessing your index is about 20GB? Solr's MMapDirectory allocates virtual memory equal to the size of the index. If there is enough free physical memory, that will be used as a cache. Sanity check: What is your Xmx? The "No space left on device" error is probably because there is not enough free file handles on your system. If it is a Linux box, try running 'ulimit -a' and look for "open files". If that number is 1024 or lower, you should increase it. - Toke Eskildsen, State and University Library, Denmark
