Zombie Processes (ZombieProcesses)
This parameter displays the total number of zombie processes currently running. Zombie processes take up physical memory and process table slots. This can be a critical problem in systems that do not dynamically increase the number of process table slots. Once the process table is full, your system cannot start any new processes, and running processes cannot spawn new processes.
Recommendations
AIX systems usually attempt to remove zombie processes on their own, but sometimes the attempt is unsuccessful. The only way to remove zombie processes manually is to reboot your system. Because each AIX system has its own characteristics and tolerances, no range thresholds have been set for this parameter. However, being familiar with your system, its characteristics, and its workload will help you determine useful range thresholds.
