Synopsis
crontabs enhancement update
Type/Severity
Product Enhancement Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
An updated crontabs package that adds one enhancement is now available for Red
Hat Enterprise Linux 5.
Description
The crontabs package contains root crontab files and directories. Crontab files
are used to schedule jobs to be executed by the cron daemon, such as cronie.
Crontabs handles a basic system function so it should be installed on your
system.
This update adds the following enhancement:
- The cron daemon had no mechanism to manage cron job rescheduling in a shared
environment selectively. Therefore, when a large number of hosts attempted to
execute their jobs at the same time, a network or server running the jobs could
become overloaded. This update modifies the run-parts script to provide cron job
randomization. When cron job randomization is enabled and configured, and a cron
job fails to be executed at the scheduled time, cron retries to execute jobs
after a random interval. The network and server overloading due to too many
simultaneous cron jobs can no longer occur. (BZ#532157)
All users of crontabs are advised to upgrade to this updated package, which adds
this enhancement.
Solution
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to
