AlkaronProblems when booting OS4.1 *solved*20110308 22:39

For a couple of weeks I have had some problems when booting up OS4.1. It is slow (as hell). It takes about 4 min. before workbench is useable. I've tried most thing, first thing is checking network-connection, as this is a very common thing that might delay. Its not the problem. I have tried disconnecting hardware, defraged the SFS2-partition etc, no luck.. I have run out of ideas.


Using OS4.1u2
Hardware: PEG2 G4
Navigate: 1-5

Does OS4 run slowly once it has booted? I assume not (otherwise it could be DMA vs PIO mode, or very low Max Transfer value, or any number of other "general" causes.).

My recommendation would be to disable all 3rd-party stuff that you can. That means disabling all WbStartup programs, and disabling User-Startup. If still no luck then move any 3rd-party Devs & Datatypes out of their folders (store them somewhere else temporarily), but if in doubt ask which ones come with OS4.

If that still doesn't help then you need to find exactly which point it is getting stuck. I suggest finding a Shell program that plays a BEEP noise (or similar), and placing it at 2 points in the Startup-Sequence. You can then hear (roughly) where the delay is happening (assuming it is in one place), and then gradually narrow 2 beeps closer & closer together, until you find the exact spot. Since you didn't report slow performance AFTER booting, I think it is very likely there is a particular command causing the problem.

P.S. The ONLY way to prove that the network connection is not the problem is by putting a semi-colon at the start of the C:AddNetInterface line in S:StartUp-Sequence. This disables networking.

I bet it's corrupted ENVARC:ringhio.appsprefs.xml file. Check if that file is abnormally big or open it in any text editor and check if there's one strange character repeated millions of times then that file is corrupted. Just delete it and remember to delete also ENV:ringhio.appsprefs.xml.

All files in ENVARC: are copied into ENV: with every boot and if ENVARC: is full of big files it will slow booting down.

Yep! Thats the one. It seems to be corrupted. A single character is repeated over and over..

ringhio.appsprefs.xml 3273909 ----rwed 23-Feb-11 12:41:24

Deleting and rebooting right now..

Yes! ..

Big difference.. Thank you very much TSK..

Shame that you could not send a copy of the corrupt file to Rigo :(
TSKRe: Problems when booting OS4.120110309 11:47  #2780

I think Rigo have said it's fixed already (in beta/next update).
