Hi,
I did understand what you need, I'm newbie to Solr and Java but not to Linux.
So please believe me, the only data that gets written on OOM is
# solr_oom_killer-8983-2016-10-10_00_02_46.log
Running OOM killer script for process 116987 for Solr on port 8983
Killed process 116987
# solr.log
<long warning about temporary segment, that I've posted ago>
# solr_gc_log_20161010_0810
