Hi
We currently host index of size approx 12GB on 5 SOLR slaves machines, which
are load balanced under cluster. At some point of time, which is after 8-10
hours, some SOLR slave would give Out of memory error, after which it just
stops responding, which then requires restart and after restart it works
perfectly. Sometimes we notice long query processing time of specific SOLR
slaves after which we restart just to avoid any forthcoming problem. Can
anyone suggest how to avoid OOM problem. Out slave SOLR are read only and we
do the incremental updations during night only. Below is the snapshot of
error we get as OOM:
