JeanLuc7 Posted August 26, 2007 Share Posted August 26, 2007 Hello, I installed OSX on my ASRock Conroe 945 in February this year, and it was very stable. But in the last few days it crashes and shows me the reboot-your-system screen every 4 hours and 5 minutes after startup. When I restart, it lasts again 4h 5min. First I thought I had installed some update or software which caused a network error or something. Then I re-installed OSX - same result. I did it again, this time leaving the system without any further installation (just Realtek Driver, USB Fix and Azalia Audio adjustments). Same result. This looks strange. I did not install any new hardware. I checked the temperature and put the system under heavy load - nothing changed the behaviour. It crashes after 4 hours and 5 minutes. And it runs perfectly stable before. There's no crash log of course... Any ideas? I have no more ideas where I should search. Thanks, JL Link to comment https://www.insanelymac.com/forum/topic/61391-osx-crashes-4h-5-minutes-after-startup-every-time/ Share on other sites More sharing options...
Agurchik Posted August 26, 2007 Share Posted August 26, 2007 look through the daemons i think some daemon after 4h5m unloads system kext(s). (/system/library/startupitems; /library/startupitems; ~/library/startupitems/, /var/root ant etc...)

JeanLuc7 Posted August 26, 2007 Author Share Posted August 26, 2007 Hi again, i checked these items but found nothing strange. Just did a new install with a different image, but same effect - 4h and 5 mins after booting up it shows the black screen and lets me reboot the system. The log files in /Library/Logs do not show any entry. So where may I look to get rid of this annoying feature? Can anybody help me?

Lactobacillus P Posted August 26, 2007 Share Posted August 26, 2007 Perhaps some memory leak in a patched file. How is the memory-use on your system?

dmy Posted August 27, 2007 Share Posted August 27, 2007 Hi i have the same problem, but the timing differs sometimes from 4 hours to 12h, i still don't know the cause, i changed my graphic card from ati x1600 pro to geforce 7600 gs same problem remains + motherboard from intel 945gpm to asus p5b-e, same problem remains, stable 100% until it enters the dark hours from 4h to 12h, sometimes i do restart the machine to prevent having the restart screen appearing in the middle of an important task, no one did or could help my case, but maybe i'll give you a hint, i have two computers connected with a router, and what makes me think it has relation with a network issue is the fact that when my pc shows the restart screen my brother's pc shows it some seconds after me, i have tried a network card dlink 528t + dlink wifi usb, and the problem still remains, which means it's not a hardware issue.

JeanLuc7 Posted August 27, 2007 Author Share Posted August 27, 2007 Hi again, I also have 2 installations, however they do not crash together - but they both do after 4h, 5 minutes. I did the following tests: 1) Fresh installation from 2 different 10.4.8-versions - I added Network, Audio and USB support only. 2) Disabled ntp and Spotlight All this had no effect. Today I check wether disconnecting the Ethernet cable would prevent the system from crashing. I also undid the changes to my network from the last two weeks. One was to change Ethernet frames on a NAS (Buffalo TeraStation) from Jumbo size back to normal size. The other was integrating a Sony Broadcast station or the PSP - I disconnected it and switched it off. Therefore the second system is still connected to the internal network. I will report if that did the trick.

JeanLuc7 Posted August 27, 2007 Author Share Posted August 27, 2007 Hi again, this time my modifications worked, both machines are still running after 16 hours. What did I do? + I set the Ethernet frame size from my Buffalo TeraStation from "Jumbo Size" back to "normal" + I switched off the WLAN Broadcast station for my PSP To re-check what was wrong I reconnected the Broadcast station 3 hours ago and I am still waiting for a possible crash. If that will work correctly, I will change the frames back to Jumbo - maybe that brings back the crashes. So check if your network uses unusual Broadcasts or frame sizes. Maybe that will do the trick for you.

olofd Posted September 6, 2007 Share Posted September 6, 2007 How do you change Framsize of your Ethernet? I have the same problem, If I leave the computer it crashes after 10 minutes. often crashes during sceensaver. Crashes when been running 1-1.5 hour. Very annoying. 10.4.10 Q6600 GA-P35-DQ6 RXXXX.kext Jas 10.4.8 Jas combo update 10.4.9 Koolkal Update 10.4.10 //Olof Link to comment https://www.insanelymac.com/forum/topic/61391-osx-crashes-4h-5-minutes-after-startup-every-time/#findComment-442718 Share on other sites More sharing options...
JeanLuc7 Posted September 6, 2007 Author Share Posted September 6, 2007 Well - first I changed the Ethernet Frame Sizes on my NAS to Jumbo, which caused the problems. As I also did several other changes, it was difficult to find out what caused the problems. But changing the settings on the NAS back to normal did the trick.

hedge605 Posted September 8, 2007 Share Posted September 8, 2007 I'm sure most of you are aware, but for those who aren't: If you have a notebook, OS X will try to put it to sleep, which will usually result in a crash (unless you are one of the lucky ones who can actually sleep). Maybe this is also true on a desktop? I had to disable sleep in the system preferences.

muitommy Posted September 9, 2007 Share Posted September 9, 2007 you better try to close the sleep functions, i did have such experiences before and i suspect it should some incompatible issue relate to ntfs-3g or bt-ing, my system crashes with no reason(i didn't know how long? i didn't for it) , but now my system is fine after i closed the sleep functions and try to use ntfs-3g , dun know if this help, but my nb can actually sleep and wake up =( weird Link to comment https://www.insanelymac.com/forum/topic/61391-osx-crashes-4h-5-minutes-after-startup-every-time/#findComment-444737 Share on other sites More sharing options...
JeanLuc7 Posted September 10, 2007 Author Share Posted September 10, 2007 Hi, I was aware of that sleep problem - I switched it off right after installation. There we see a correct going-to-sleep but a never-wake-up. Here I had a real crash with the black screen of death requesting me to restart the computer. But finally I fixed it :-) JL Link to comment https://www.insanelymac.com/forum/topic/61391-osx-crashes-4h-5-minutes-after-startup-every-time/#findComment-445543 Share on other sites More sharing options...
