Prelink is eating up my system!

Hermitian · 04-05-2005, 04:16 PM

About half and hour to an hour after I bring up my FC3 system, prelink pegs the processor out at 90-100%. It stays this way for hours. It might go on for forever, but becasue of certain reasons I switch back and forth from FC3 to windows fairly often.

I can tell it hurts the responsiveness of my system. What is this and what can I do about it?
Thanks.

Some stats on my system:

uptime:
17:11:17 up 1:44, 3 users, load average: 1.96, 1.77, 1.43

IBM R31 Laptop
FC3
KDE 3.3
384MB RAM
1.13 GHz PIII

Prelink is used to speed up the load time of certain apps and libraries. Note that some apps are NOT compatible with prelink. The prelink cache needs to be updated occasionally to accomodate new apps/libs etc. This is done with a cron job.

If you want to disable it, I have some notes here:

Edit /etc/sysconfig/prelink
Change PRELINKING=yes to PRELINKING=no

You can move the cron file of prelink from the /etc/cron.daily/prelink to /etc/cron.monthly/prelink.

Thanks for the suggestions so far. I understand that it does have a purpose, but I was just wondering if it is normal for prelink to run for so long and slow the system to a crawl?

I tested it today and it actually only ran for about an hour and a half. It was fine after that.

Prelink is not laptop friendly. My HP contantly keeps speeding up the fans, so I removed prelink.
