VuFind Local Catalog Outages

This morning at 7:14AM Monday, December 8th, the SOLR search index for VuFind "local" catalogs failed (there is a separate SOLR index that handles deduplicated "consortial" searches). The java process controlling the index was pinned at 100% CPU and no requests were being processed. At 7:34AM this morning, the SOLR service was restarted restoring service. At 11:22AM the service went offline again and was restarted.

Looking at the logs, we see that there are java "OutOfMemoryError" messages. The java allocation for SOLR has been increased from 14GB to 20GB of RAM and we will continue to monitor this service.
