推荐答案

尝试增加记忆力

设置环境变量 JAVA_OPTS="-Xms256m -Xmx500m" 这意味着堆起始大小为 256 MB，最大 512 MB.或者编辑您的 catalina.bat 或 .sh 并在那里添加这一行.

Either set the environment variable JAVA_OPTS="-Xms256m -Xmx500m" which means heap start size is 256 MB, max 512 MB. Or edit your catalina.bat or .sh and add this line there.

你必须处理这些值，几周前我有一个 SOLR 索引器工作，需要大约 2 GB 的数据和 700MB 的堆.

You have to play around with these values, some weeks ago I had an SOLR indexer job, about 2 GB of data, 700MB heap were required.
