Linux (the out of memory killer, or oom-killer) is deciding to kill the
java process because the entire machine is out of memory. Normally it
kills off the process using the most memory. This will only happen when
all RAM is fully allocated to programs as well as all available swap
space. At this point, this is not a direct problem with Solr. It
*could* be a problem with Java itself, but that is not very likely.
Because Java is set to use only 8GB out of the 12GB you have on the
machine, this suggests that you have at least one other memory-intensive
application on the same server. Are you using the same hardware to run
a website and/or database? Solr works best on dedicated hardware.
