Hi guys, |
2 |
Not particularly a show-stopper, but I recently did an emerge, and one |
3 |
of the packages that was upgraded was udev. Intermittently, at least |
4 |
since the upgrade, my udev has been giving me prolonged spikes of cpu |
5 |
usage. It doesn't hog the whole cpu or anything, but it does use up |
6 |
some 60-70% of my running cpu. This is when my actual CPU (3.0GHz P4 |
7 |
HT) is about 60-70% also, so the actual CPU% used by udev is something |
8 |
close to maybe 25-30%. Normally, udev is about 6% of 60% though. |
9 |
|
10 |
Now most of the time, just like now, I'm logged in to my PC from my |
11 |
weaktop accross the room, and my other user, my brother, physically |
12 |
sits on the machine, meaning there's two of us. We've been doing this |
13 |
for several months now without complaint, so I'm pretty sure it's good |
14 |
enough to handle us both. However, recently, at least since my last |
15 |
emerge, my brother says that the responsiveness sometimes goes down at |
16 |
certain points and when I go top from across the room I see udev going |
17 |
to about 60-something mph. So what I do is I just restart udev, music |
18 |
dies for about half a second, but everything goes back immediately |
19 |
without problems. Essentially painless. |
20 |
|
21 |
The second time I had to restart udev I suspected something was wrong, |
22 |
so I set my udev.conf to go |
23 |
udev_log="err info debug" |
24 |
And restarted it. |
25 |
|
26 |
So the third and fourth time udev gave me a spike, I checked my system |
27 |
logs for anything related. Nope, nothing doing. |
28 |
|
29 |
This usually only happens when my other user is around, not when I'm |
30 |
just sitting across the room. Most of what we do is just firefox, |
31 |
although just recently I've been using digikam (which takes forever to |
32 |
start up because of the sheer size of my pictures collection, but hey, |
33 |
I'm not one to complain). |
34 |
|
35 |
I figure this may probably be related to my udev version bump. I |
36 |
forget my previous version, so it might be even a lower version bump |
37 |
than 140. Or maybe it's been going on for a while and I just didn't |
38 |
notice it. Anyhows, has anyone (if anyone has) noticed any strange |
39 |
udev CPU activity before? What have your experiences been with it and |
40 |
what do you think it's usually related to? |
41 |
|
42 |
=== some out-of-the-ordinary things that might be related, but I don't think so |
43 |
- we did buy a new hard drive just last month. No problems with that one so far. |
44 |
- now that I think of it, my xorg drivers and other stuff probably |
45 |
also got bumped with udev. |
46 |
- i've been ignoring a bunch of tracker segmentation faults in my |
47 |
/var/log/messages, related to extracting exifs |
48 |
- a bunch of samba shares |
49 |
- we haven't logged out of our xsession in about a week. |
