java - Tigase xmpp 服务器在使用 Tsung 进行测试时崩溃

Question

我正在尝试测试 Tigase XMPP 服务器 5.2.0 的功能。

我正在使用 tsung 1.4.2 运行测试，以达到 20K 用户的连接(一旦 20K 工作正常，我将尝试使用 150K 进行检查)。 tigase 在大约 6000 个连接后崩溃。有人可以帮我找出问题所在吗？

详细信息:tsung的参数为:(每秒12个连接，连接1666秒=20K用户)

在tigase中参数是:(init.properties)

--admins=admin@my_domain
--virt-hosts = my_domain

--user-db=mysql

JVM 的内存设置太低。您的安装可能因 OOM 而崩溃。
