nautilus process uses 100% CPU for 30 sec - 2 minutes on computer startup.

[Hans-Kristian Bjerregaard]

Binary package hint: nautilus

On start up the nautilus process uses all the computers resources doing apparently nothing.

Im using Ubuntu 8.10 with the package version 1:2.24.1-0ubuntu1

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please answer these questions:

 * Is this reproducible?
 * If so, what specific steps should we take to recreate this bug?

 This will help us to find and resolve the problem.

[Hans-Kristian Bjerregaard (bjerregaard-6)]

It is reproducible to me, i just have to boot ubuntu. It just happens after i log in.

Is there any information you need about my system or settings that may help you reproduce the bug on other machines?

[Sebastien Bacher (seb128)]

do you know how to use gdb? could you get a nautilus stacktrace while it's using ressources?

[Martin Mai (mrkanister-deactivatedaccount-deactivatedaccount)]

Instructions on how to do a stacktrace can be found at https://wiki.ubuntu.com/DebuggingProgramCrash. Thanks in advance.

I have the same problem on a 64-bit Ubuntu 8.10 System (2.24.0-0ubuntu2).

I tried to produce a Backtrace as described under 'Already running programs' in https://wiki.ubuntu.com/Backtrace, but after pressing ctrl+c in step 5 gdb quits so I cannot retrieve the Backtrace.

So I tried to produce a Strace. Then the nautilus process did not stop by itself. When the logfile exceeded 90 MB I stopped it manually. I am attaching the first 1 MB of the Strace logfile.

Hope somebody can make sense of this.

I think I have the same problem,
     constantly 40% to 50% nautilus usage, doing nothing.

It seem related to a network share I have mounted. I found its name into a strace output.

When I realized this, I've tried to access it from nautilus. After this access, CPU utilization went suddenly down.

Hope this helps!

[Sebastien Bacher (seb128)]

the strace log is not useful, did you read the wikipage indicated, it's about getting a stacktrace using gdb
could you try if that's still an issue in jaunty and get a new log if that's the case?

My experience is similar. Using top, I've noticed the following:

1 - Open a folder on a remote machine. Remote is a windows server.
      CPU goes up to ~5% and stays there.
2 - Close the window. CPU stays at ~5%.
3 - Open a folder on the local machine.
      Nautilus utilization becomes negligible.
or

1 - Open a folder on a remote machine. Remote is a windows server.
     CPU utilization goes up and stays up.
2 - Open another folder on the local machine.
     CPU utilization becomes negligible.

It seems that after opening the remote folder, opening a local folder returns utilization to < 1%.

Both the local folder and remote typically reside on my desktop, when not open.

While in my testing, 5% is not outrageous, but I've seen utilization sit a 20+%. Noticed since the fans speed up :-)

Same problem on Hardy (8.04.2). 100% cpu usage for a short period right after logging in.

$ ps uax | grep nautilus
pete 18495 89.2 3.6 98016 37784 ? Rl 11:42 0:08 nautilus --no-default-window --sm-client-id default2

[Brian Curtis (bcurtiswx)]

Since this bug has been left as incomplete for a long time, and there has been no completed gdb for this issue in hardy, I am marking as invalid. Please feel free to open this bug if there is still a problem AND a correct gdb is produced and attached.
