Opened: Mar 26, 2017
Severity: 4-Minor

Symptoms

ADMd daemon on the device is spinning up rsync processes and not cleaning them up properly, which can result in zombie processes.

Impact

Although there is no technical impact, there are many zombie processes left behind.

Conditions

The rsync process ends via exit (which might occur if there is an issue with the process).

Workaround

Restart admd to remove all existing rsync zombies: bigstart restart admd

Fix Information

admd now handles the SIGCHLD signal from rsync, so the issue no longer occurs.
