Whiteboard:
Fixed In Version: autofs-5.0.5-133.el6_9 Doc Type: Bug Fix
Doc Text:
Previously, autofs did not hold a lock long enough during a master map re-read. Additionally, autofs unnecessarily took a lock for map read operations. As a consequence, the original lookup failed to complete, and autofs did not respond. This update corrects the locking of the master map and map read operations. As a result, autofs no longer hangs due to map dependencies.
