<p class="MsoNormal">UK’s locally installed instance of ArchivesSpace has performance issues every couple of months, slowing down until eventually the application is fails. The fix is a full restart. Our programmer has indicated the failure is caused by “garbage
 collecting”. Previously we’ve added RAM to our VM. We’re interested in finding out how other institutions with a similar sized SOLR index are running ArchivesSpace. And if they have/had similar problems.<o:p></o:p></p>
