Hello Guys,
My Route(use MT7621) start well(just look well), But something happened abnormal, The abnormal phenomena are as follows:
1. when i enter / , i can not exec ls successfully(it can`t present results, just block)
2. so i I go into the directories under the root directory one by one, i found can not enter /overlay and /root(just block, other directories can enter normal)
3. my own program also behave abnormal, also just block(about open mysql table)
4.restart the system, it can be back to normal, Seems to happen by accident
So, can someone give some advices, and how to troubleshoot and resolve it?
