All CPD processes on Multi-Domain Management Server are crashing very often Technical Level
Symptoms
  • The CPD processes of the MDS and all CMAs are restarting every 10 minutes.

  • The Multi-Domain Server's CPD processes status is down in the output of mdsstat command.

  • The cpwd.elg file shows:
    [ERROR] CPD (pid=12345) did not send keep-alive message for 1 number of times
    These messages repeat every minute until the 10th time, when cpwd terminates CPD.
Cause

By design, the CPD process will query the hardware sensors for status.

In a Multi-Domain Management environment, multiple CPD processes are querying the same sensors causing a lock.
