I have solr running on a single machine with 8GB of ram. Right now I have about 1.5 million documents indexed, which had produced a 30GB index. When I look in top, the tomcat process which is hosting solr says that it's using 38GB of VIRT, 6.6G RES, and 2GB SHR.
The machine is showing a completely full swap file and very little memory free. Is this because solr is trying to load the entire index into memory? The searches are still responsive, so it doesn't seem to be affecting performance. Thanks.
