Hello Solr users crew, I have a single-node Solr 9.x instance running on a hosted virtual Debian Stable server.
The server technical specs are as follows: 2 vCPU 4Gb RAM The Solr instance has about 180,000 documents which get refreshed once a day via an automated script. Each day about a few thousand documents may get added, a few thousand may get deleted. The amount of docs will stay pretty stable or grow slowly. I have a Python/Django app using Solr as a backend for document search. What I'm finding is that at least once a week, the Solr process gets reaped by the Linux kernel due to an "out of memory" condition. My app produces an Error 500 and I then have to manually restart Solr. My Solr instance is pretty much vanilla, it's configured using the following params: /etc/default# grep -i heap solr.in.sh # Increase Java Heap as needed to support your indexing / query needs #SOLR_HEAP="256m" /etc/default# grep -i mem solr.in.sh # Expert: If you want finer control over memory options, specify them directly #SOLR_JAVA_MEM="-Xms512m -Xmx512m" In the Solr web dashboard the JVM-Memory graph is currently showing: JVM-Memory 20.9% / 107.13 MB Then in grey: 512.00 MB 512.00 MB What can I do to stabilise things? Kind regards, Imran
