Opened: Mar 26, 2017 Severity: 4-Minor
ADMd daemon on the device is spinning up rsync processes and not cleaning them up properly, which can result in zombie processes.
Although there is no technical impact, there are many zombie processes left behind.
The rsync process ends via exit (which might occur if there is an issue with the process).
Restart admd to remove all existing rsync zombies: bigstart restart admd
admd now handles the SIGCHLD signal from rsync, so the issue no longer occurs.
