udevd consuming lot of CPU
I am running Fedora Core 4 on a Dell PowerEdge 1750. Recently, I have noticed (from running the top command) that the udevd process is consuming a lot of CPU - approximately 30%. I have never seen this process taking so much of CPU before.
- Kernel version: 2.6.11 - udev version: 058-1 - What could be causing this? - Is this an hardware issue? - How do I resolve it? Thanks for your time. svangati. |
As far as I remember it is a bit old udev for rather fresh kernel.. I had some old udev that made the box boot 3 minutes (2.5 minutes doing udev). Try upgrading both (or at least udev) and post if the results aren't good.

Thanks for the response. I updated the udev package to version 071-0.FC4.3. Right after the upgrade, I ran 'top' and saw that
udevd was consuming less between 0.3% - 0.7% of the CPU - much less than the 30% prior to the upgrade. But over the course of the day, it started taking up more percentage. Right now, I see that the range is between 8% - 12%. I have a sinking feeling that this is going to grow... Also, on the other systems that I have, I see (from running top) that udev is constantly at 0.0%. Does this indicate any hardware related issues on the box that udev is trying to take up CPU resources? If so, what hardware would that be? Thanks for your help. |
Any further info on this? I've just started seeing the same thing over the past 2 weeks. udev consumes much less than 1% CPU after a reboot. Within a day it's consuming over 10%. After two days everything is so unresponsive I have to reboot.
I'm on udev 071-0.FC4.3 and kernel 2.6.17.1. I don't see that yum has updated udev in a long time. I can't imagine what changed (I upgraded the kernel is response to this problem). My next bet is to try FC5. Davek |

Installing the newer version of udev did not help. I finally took the plunge and rebooted the server (it was a production box). Since then, I have not seen udev chewing up CPU. Not sure why and how the reboot helped. Sorry. Couldn't be of much help. Sudheer. |
