1.4 Problem in Process Operation
If a problem occurs in the process operation of the APC system, the system may not
function correctly. Since every process keeps a log record of all problems, use the
respective log information to identify the problem.
Symptoms
The system does not function correctly or some of the commands do not work.
Possible Causes
The problem occurs in process operation for the following reasons.
Core dump signal
Control signal (displays back-trace log)
Thread failure due to dead-lock or endless-loop
Solutions
1) Execute the ‘show process’ command to check the process ‘Status’.

whether the log information exists. If the process log information exists, execute the
‘show processes log id’ command to check the problem and take necessary actions.
