处理方案：

这是最大线程池不够导致的，可以尝试增大线程池或增大队列大小

法1.1：能登录管控台

菜单栏》配置》server-config》线程池》http-thread-pool》最大线程池大小

法1.2 调整队列大小

法2.1：不能登录管控台，在配置文件中修改

修改ApusicAS/aas/domains/mydomain/config的domain.xml中server-config模块的http-thread-pool参数（修改配置文件前最好先备份一下，备份到非中间件目录下）

法2.2

修改ApusicAS/aas/domains/mydomain/config的domain.xml中server-config模块的max-queue-size参数（修改配置文件前最好先备份一下，备份到非中间件目录下）
