I don't think that heap size is the problem. Start scripts are like this:
{code:java}
su - solr -c "bash -c 'cd /opt/solr-8.2.0; bin/solr start -m 64g -cloud -p 8983
-s ../solr-data/instance-$(facter fqdn)-1/solr/ -z
srv-solr1.qeep.net:2181,srv-solr2.qeep.net:2181,srv-solr3.qeep.net:2181 '"{code}
In normal operation heap usage is about 30-40%.

> JDK 13 stability/recovery problems

> Key: SOLR-13862
> URL: https://issues.apache.org/jira/browse/SOLR-13862
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Affects Versions: 8.2
> Reporter: Bernd Wahlen
> Priority: Major
>
> after updating my cluster (centos 7.7, solr 8.2, jdk12) to JDK13 (3 nodes, 4
> collections, 1 shard) everything was running good (with lower p95) for some
> hours. Then 2 nodes (not the leader) going to recovery state, but ~"Recovery
> failed Error opening new searcher". I tried rolling restart the cluster, but
> recovery is not working. After i switched to jdk11 recovery works again. In
> summary jdk11 or jdk12 was running stable, jdk13 not.
> This is my solr.in.sh:
> GC_TUNE="-XX:+UnlockExperimentalVMOptions -XX:+UseShenandoahGC"
> SOLR_TIMEZONE="CET"
>
> GC_LOG_OPTS="-Xlog:gc*:file=/var/log/solr/solr_gc.log:time:filecount=9,filesize=20M:safepoint"
> I also tried ADDREPLICA during my attempt to reapair the cluster, which
> causes Out of Memory on JDK 13 and worked after going back to JDK 11.
