我用TE2440 II 在超级终端里 挂载上 NFS后，执行共享文件中的一个 shell 脚本（挂载的共享文件大概有60M），出现了NFS 不稳定的情况！具体如下：
nfs: server 192.168.0.12 not responding, still trying
nfs: server 192.168.0.12 not responding, still trying
nfs: server 192.168.0.12 OK
nfs: server 192.168.0.12 not responding, still trying
nfs: server 192.168.0.12 OK
nfs: server 192.168.0.12 not responding, still trying
nfs: server 192.168.0.12 OK
nfs: server 192.168.0.12 not responding, still trying
nfs: server 192.168.0.12 not responding, still tryin
这个问题是由什么引起的？应该如何解决额？？？？
