Description Mustafa Mahudhawala 2005-07-13 09:15:56 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0

Description of problem:
The result of crond not explicitly opening file descriptor 0, is that
the cronjobs inherit a closed fd 0 (stdin), which tends to be an issue
in some cases. eg. anacron invoked from /etc/cron.daily/0anacron fails with error 

anacron: Can't close stdin: Bad file descriptor

This issue is same as in bug #145992 reported and fixed against RHEL 3.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
Same as in BZ #145992

The patch provided in #145992 (just to address this issue) works fine here.
Comment 2 Jason Vas Dias 2005-07-27 17:44:18 EDT
I don't think this bug warrants an errata update for RHEL-2.1 .
Should customers require that this bug (and MANY others) be fixed, they
should install vixie-cron-4.1-2_EL2, available from:
This is on a CVS branch tag (not the head release) and is built in
dist-2.1-scratch .
Comment 3 Marcela Mašláňová 2006-08-28 07:39:12 EDT
It should work in vixie-cron-4.1-2_EL2. 
It's inactive one year, so I close it.
