PCP fails to start on systems running other processes with the same names

Solution Verified - Updated -


  • The PCP pmcd process is not running any more. The result is that pmlogger_check gives errors that it cannot connect to pmcd anymore. There is a pmcd in the ps output, but this is from UniSpool and not from PCP.
