SSH to Intel Xeon Phi card sometimes is kicked out and require password to access again

Dear all,

Please help me with the problem: sometimes, I access the Xeon Phi cards by ssh, however, it takes a short time and kicks me out, the user for access is just a normal user. It has not occurred with root user. After that, I restart the service MPSS and it is ok.

Actually, I don't know the reason why, please help me with this problem. Below is the information of our Xeon Phi cards:
