I don't know if the zombie process is the reason why the display cannot be accurate.
However, in most cases, the cause of the zombie process is due to the detection of a memory leak or because the process has become unresponsive (i.e., it often occurs when PAN-OS kills the process by detecting them).
For this reason, it is recommended to grep the log on FW with ”fail”.
grep mp-log m*detail* pattern fail
If you are actually using the PA-220 and not in a lab environment, I would suggest that you output the Tech Support File, decompress the archive, and then grep it on your computer (since the PA-220 is poor).
The name of the log file containing the process details should probably correspond to "m*detail*".
I don't remember exactly what it is, so it would be a good idea to ask you to find a file with a similar name.
