Hi,
I did a simple test on a three node cluster using Solr 7.2.1. The JVMs
(Oracle Corporation Java HotSpot(TM) 64-Bit Server VM 1.8.0_162
25.162-b12) have about 6.5GB heap and 1.5GB metaspace. In my test I have
1000 collections with only 1000 simple documents each. I'm then
triggering collections reloads via SolrJ using a fixed number of
threads, as this has shown memory issues in the past. Even with two
threads the nodes eventually die with an OOM Error as they are running
out of metaspace. I found the following Jiras that might be about the
same issue:
https://issues.apache.org/jira/browse/SOLR-10506
https://issues.apache.org/jira/browse/SOLR-9117
https://issues.apache.org/jira/browse/SOLR-6678
The first two are flagged as fixed in 7.0.
Any ideas, beside not doing reloads?
regards,
Hendrik
