Just happened yesterday night. When I switch on my SAM and loads AmigaOS 4.1, while Workbench is loaded SAM already uses 100% CPU!!!

And the other thing I noticed is that my memory is getting shrinking and shrinking all the time.

Probably something conflicts in WBStartUp Prefs? Any ideas?

Thanks.

If a computer does some heavy work I would like to see it using all its resources. If a program uses 100% CPU power it mighgt just means there is nothing like network, or disk I/O making the CPU wait.

I checked now, as I left it switched on to check, and now the CPU and memory came back to normal state!

How I can check what causes this crawling to my system? Internet works normally so it's not.

I don't have a clue about my DVD-RW drive, as it's the same 1 year now (no problems so far).

exactly what it should do after the heavy work is over

I just wanted to explain: 100% CPU load and "crawling" are not the same.

How do you define "craqling" ?

Did you start you CPU monitoring tool manually or have you included it somewhere in the startup?

Maybe some automaically started tools inyour system a causing a lot of CPU load.

I always had it in the dock (it's CPU docky) for a long time; no problems so far.

For how long is the CPU at 100% usage?

Does it drop just a second or two after all WBStartup items have loaded or does it take many seconds or up to a minute before it drops to normal?

It if takes a long time, prehaps you have time to start Scout, click Tasks, click the "tc_State" column, click Update and see what task shows as "ready" for a long time.

Note that it is normal for the CPU to be at 100% while booting and loading all WBStartup programs. There is no need for the CPU to do things slower than maximum speed unless it has to wait for some I/O of course

I never checked it, but approximately 5-10 minutes for sure.

It's normally at 100%, but sometimes can go to 80% or 90%, but for just a second!

I will try that, but I'm suspicious about the DVD-RW drive, because 2 days now it's not behaving very well. When I inserted a CD-ROM inside, I got a very big lag in my system.

I never had any problems. When Workbench was loaded I was ready with 1% CPU all time.

Thanks.

Yeah. Some years ago I had someone complain about FolderSync1 using 100% CPU, but in fact this is perfectly normal for anything which does heavy processing & isn't often slowed down by I/O (disk or network access).

That said, amazingly AmigaOS can often remain fairly responsive DESPITE a *buggy* program hogging most of the CPU time. So you may not always realise something is wrong unless you look at the CPU meter.

The key thing is (as you said) it shouldn't be using 100% CPU unless you know it should be doing something, such as booting & loading all the WBStartup programs. But once disk activity (HD light) has ceased after booting, the CPU usage should drop too. If it doesn't then something is buggy, then you need to try disabling all the WBStartup items (and perhaps the S:User-Startup sequence).

Ideally you could just use Scout to find the CPU hog, but for some reason this doesn't work even in the OS4 version, which is really annoying . One would have thought there would at least be a simple "Top" utility, but I haven't found one.

Could you check all files in ENVARC: ? Of course it could be your DVD drive causing trouble as well.

I will try that too at night. Thanks everybody.

You were right my friend. I found a file in ENVARC: and it was approximately 7MB! I thought that was not normal, the file was ringhio.appsprefs.xml. I deleted it and now everything is normal again.

But what happened with that? Any clues how this file went about 7MB?

That file size on my micro is only 4.3K. It contains a list of all the apps that ringhoi answers too. There was a problem with the ringhoi server eating memory if off screen dragging in the GUI prefs was turned off, but thats been fixed in later updates (os4.1). You have a sam, so the server still might have bugs on that system. You can delete the file & start the Notification prefs & do a save to start fresh. Just keep your eye on that file size to see if it grows again.

The other file, ringhio.miscprefs.xml, is about 700 bits here. Play it safe & save the old files somewhere just in case.

Perhaps you could undelete this file (if using SFS or JXFS) and send it to Rigo or someone else on the OS4 team? Then they can fix the bug (if it isn't already).

I had this same problem some time ago. Don't know what caused it.

The ringhio.miscprefs.xml file is exactly 665 bytes, dated 15-Nov-2009.

The other one, ringhio.appsprefs.xml, is now 1119 bytes, dated already a couple of hours ago (23:13.55).

I'm surely it grew up in size, as when I deleted the big file, the system already created a new one in ENVARC: and it was not more than 500 bytes long!!

Just ringhioin in.

My ringhio.appsprefs.xml, is now 2004 bytes, dated 7 Jun 2010.
The ringhio.miscprefs.xml file is exactly 665 bytes, dated 30 Mar 2010.

I wonder if a newly loaded program adds to the file size, but deleting
a program does not change it.

Or something like that.

I have one and I use it often. Mine came directly from Jörg, but he might have it on his website. In any case I'm sure he'd be happy to release it.

No the .xml definately changes here having just viewed mine. I had a tidy up the other day when I noticed lots of programs in Ringhio prefs that I don't use/are not installed anymore, i.e. things I've donwloaded, tried out and then deleted.

Similar happens with APPDIR: the path files accumulate as you use new programs and stay when a program's deleted. I think some sort of automatic scan and clean-up feature is needed to prevent problems like this freak 7MB Ringhio prefs file, could make a nice addition to AmiUpdate?

Unused entries are deleted after a period of inactivity. I think it's a few months, though.
