I encountered an automatic restart problem of ProcessMonitor in PM nodes except PM1. It seems that the process of ProcessMonitor in PM nodes will be restarted every several minutes. Is it a routine action?

The debug messages are as follows:\\
ProcessManager[28993]: 28.246599 |0|0|0| D 17 CAL0000: distributeConfigFile called for pm2 file = Columnstore.xml\\
ProcessManager[28993]: 28.296048 |0|0|0| D 17 CAL0000: sendMsgProcMon: Process module pm2\\
ProcessManager[28993]: 28.296282 |0|0|0| D 17 CAL0000: pm2 distributeConfigFile success.\\

ProcessMonitor[28677]: 48.376324 |0|0|0| D 18 CAL0000: statusControl: Set Process pm2/ProcessManager State = HOT_STANDBY PID = 17378

Can you help investigate the problem? Thank you very much.
