提交时Solr Cloud shard更新错误

Question

根据本指南，我已经在一台机器上部署了一个具有2个shads和2个切片的solr cloud设置：http://outerthought.org/blog/491-ot.html

当从2个并发客户端一次性提交500+文档时，solr云抛出了这个异常。任何形式的帮助都是值得感谢的。谢谢。

Answer 1

当我没有为solrj客户端提供足够的内存时，我也会遇到同样的错误。我需要在我的环境中放一些类似的东西：

JVM_OPTS="${JVM_OPTS} -XX:NewSize=512m -XX:MaxNewSize=1G -XX:PermSize=512m -XX:MaxPermSize=1G -XX:+DisableExplicitGC -Xms4G -Xmx6G"
