[GitHub] [incubator-dubbo] carryxyh commented on issue #2771: Dubbo invoke timeout, Waiting server-side response timeout by scan timer

看看是不是请求增多，连接池维护的连接如果都被使用中，就会阻塞直到连接池中有连接。
如果是这个问题，把db的连接池连接数增大。
导致连接释放慢的一般是慢sql或者请求多，连接池的连接不够用。看你的情况应该不是，那可能是请求增多，因为你这边好像没有看到特别慢的sql。你可以看看网关的数据或者手动埋点看看那个时间段的请求是不是比平时多
