Openfire Java内存不足错误 – 任何解决scheme？

我有Openfire的巨大问题，每时每刻因为缺乏内存而崩溃。在Java日志中，我有以下错误日志。然而问题是

Openfire是32位，我不能运行它为64位。
因为我可以给Openfire的只有32位最大内存是4GB。
我的系统是非常强大的32 GB RAM，所以我不能再增加
只有最多100个用户使用openfire，但似乎还不能处理它
我每5分钟运行一次cron作业来监视这个服务，然后每隔一段时间重新启动一次

任何解决scheme如何优化内存使用开放和停止崩溃？

错误日志如下

Openfire是用java编写的，并不是32位的。如果您使用64位jvm，它将以64位模式运行，您可以尽可能多地使用它。尝试安装64位jvm / jre
