Parinoid experiences

[Ernst0]

I had "lockups" on th eold HP quad core AMD and so I bought an 8 core machine.
On F-14 someimes it would hang and I would need to wait seconds or a minute for it to resume playing music for example be it streaming or even sometimes from the harddrive.

I assumed it was the abused cpu which was up high in the heat of the room for no good reason for years.

So with the new 8-core and F16 the problem is still there but worse.

I am downloading and streaming a radio station and while trying to type to vim it seems to be waiting for something and will not display what I type nor respond to any control.

The frozen moments are 10 second to 30 seconds or more.

The parinoid moment here is : IS Vim waiting to update it's backup files or is somehow what I type being transmitted and vim is waiting for a break in the outgoing stream?

I get the whole system locking up for seconds worse under F16 tyhan F14 and I was expecting snappy proformance.

So 1. I don't understand what is happening and 2. I am only guessing as to what could be going on.

Any ideas?

Something to try:
If you have a CDROM/DVD drive, unplug it.

Ah!!!

I am waiting for a seperate controler to arrive. UPS emailed it would be delivered today.

So I will be putting 2 dvd's on that controler.

Perhaps since I am using Logical Volume maybe it is the most CPU intesnive?>

Okay then I had the bright idea to put the dvd's on a seperate controler and keep the 4 hds and soon a backup drive on the SATA motherboard controller

The hangups are very annoying when trying to write code. It does seem it is waiting for write access.

Thanks for the suggestion and I will report what changes if any happen.

sleepy afaik..
It wont wait for write access while typing.
It just wont let you save it as long you dont have write permission.

Are you by chance using Gnome?

I had issues like that until I disabled the at-spi (assistive technology) applications, I also got better response after disabling the ibus (input method) and tracker (indexes your drives for faster searches) applications as well.

open a terminal and run

gnome-session-properties

uncheck the at-spi, ibus, input method and tracker programs, then restart gnome shell.

If I am typing this "Hello crule world" I can type it but I will not see it for seconds. Also I cannot get access to the controls in vim during these seconds so I have to wait.

The Human should never wait for the machine in my opinion.

No controler today just the laptop screen.Tomorrow I should see itt..

I have time to consider what to do. Thanks friends.

So many changes to the equipment all at once is stressful.

@Dbelton there is AT-SPI D-bus bus, AT SPI registry. which one to uncheck?

[sonoran]

Don't know if this was ever resolved:

uncheck all of them.

But only if you don't use the assistive technologies.

Same thing with the imsettings/ibus stuff. If you don't need to input text in a different language, you can disable that stuff as well.

And the tracker stuff will bog the system down at times, too. So I disabled all of that mess since I don't use it to search my drives anyway. (If I don't use the search, why waste the resources to index? )

Edit:

Not sure if that was ever resolved, either, sonoran. That thread just abruptly ended, without knowing if they ever got their issue fixed. I hope they did, but wish they would have said what the resolution was.

I am reading and tomorrow I will review but it effects the video in movie player. It will seeming buffer the movie , wait and then speed play. I had simular in F14 but the new cpu makes the speed play like true fastforward to some index.
It would seem the output is buffered in some way.

Well it is late tonight so tomorrow.

Oh the video was backing up with no load on the network nor anything running heavy load on the cpu and is like before on f14

Could it be a bad HD?

[DBelton]

it is possible that it could be a bad hard drive and it is having to retry the reads.

Also, most of the video players do buffer the video in some way. You can usually configure it in the settings for the video player.

Do you get the same results when playing a video from a local drive rather than one over the network? If it plays fine from a local drive, then it could be a network configuration issue. (I have had some videos stall when streamed from a samba server on one of my NAS drives before, but it would play fine if it was from a NFS share or local drive)

Howdy,

There is an OLD (ten years old, but still there) bug regarding 10 second freeze-ups with certain old CDROM/DVD drives. The problem will go away if you unplug the CD/DVD device and reboot. If it doesn't, then it is not that.

[Ernst0]

I am yet to unplug the dvd but will today when the second controller arrives. I will update when I do.

I see this error but does it apply to the text issues? Is this something I need to change? Am I supposed to change the mode?

Need writable directory, but '/var/spool/abrt/oops-2012-02-14-18:22:54-1107-0' is not writable. Move it to '/home/ernst/.abrt/spool' and operate on the moved copy?

[flyingfsck]

I had a periodic freeze problem like this long ago with a specific DVD drive. After replacing the drive with a different model, the problem went away. The actual bug is in the DVD device driver and it has never been fixed, since it is impossible/hard to find. So if you have one of these bad drives, then your machine will periodically freeze. So, remove the DVD drive and see if the problem stops.

I freely admit I am trying to come up to speed on building a new system.
I've been snug with the common distros up to and including F14. F16 is not a easy fit here at this time.
The problem has gone away with the change to RAID 1 for the harddrives but I am getting file system errors every time I add software.

I don't know what the real cause was but my system is not stable so I cannot say one way or the other at this point.


Thanks every one.
