远程连接一台linux机器，centos 5.6. 刚登录session就飞了，有的时候就不飞，具体报错如下，求大侠帮忙看看。
我尝试过的方法：
1. 不是ssh idle session问题，应为是session刚登录就飞了。
2. 也设置过ClientAliveInterval的参数，重启SSH都问题依旧。
# grep -i client /etc/ssh/sshd_config
#ClientAliveInterval 0
#ClientAliveCountMax 3
ClientAliveInterval 300
ClientAliveCountMax 20
3. 不是防火墙问题，局域网连接也有一样的报错。
4. 局域网IP没有冲突。
报错信息:

Connection to 10.2.135.5 closed.
