Symptoms

Under certain circumstances, devmgmtd might leak file descriptors.

Impact

devmgmtd may restart, logging an error that it has 'too many open files'. Although the failed reaction is correct (restarting because there is an existing error condition), the system presents an error message that does not indicate the issue.

Conditions

This might occur when attempting to add a device to trust by specifying a hostname instead of an IP address, where this hostname is not valid.

Workaround

None.

Fix Information

devmgmtd no longer leaks file descriptors in a certain error path (which would sometimes cause it to dump core).
