Cron Job

[mikechansf]

I have been receiving this message on the admin email account.

/etc/cron.daily/prelink:

/etc/cron.daily/prelink: line 47: 18167 Aborted /usr/sbin/prelink -av $PRELINK_OPTS >>/var/log/prelink.log 2>&1

I am not very familiar with cron job and don't know what this cron job is for. Can someone give me some insights? Thanks.

Hi,

I get this message from time to time as well.

Your version of linux tries to prelink applications and libraries to make them start faster. Not really needed on a server in my eyes.
This is not working for all applications and so you get this error.
I am thinking of simply removing the cron job.
This will do no harm.

I was also getting this error message on my RedHat Enterprise Linux 4 server. As the previous poster said it's a cron job that you can safely remove. I removed it by deleting the relevant file from /etc/cron.daily.

Besides getting a somewhat annoying message, does the error cause any problems. If not, why remove it?

For me, the only reason to remove it was to stop the annoying message. If you don't find it annoying, then no reason to remove it right?

I stopped the noise by editing /etc/prelink.conf and added lines to blacklist specific files. I have not read enough about this process to disable/remove from cron.daily, the process seems to be related to creating links to C++ libraries prior to exececution of C++ code.

cat /var/log/prelink.log | grep 'could not'

add the files to /etc/prelink.conf (your files may vary)

-b /usr/lib/libldap-2.2.so.7
-b /usr/lib/libnfsidmap.so.0
