So far it happened to me 3 times, each time in same situation, so for me it is 100% predictable (IOW if I copy given directory I am sure system at some point will be frozen). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

https://bugzilla.novell.com/show_bug.cgi?id=687894 https://bugzilla.novell.com/show_bug.cgi?id=687894#c3 --- Comment #3 from Maciej Pilichowski 2011-04-16 07:48:42 UTC --- * 400 files, 200GB total -- system freezes Among others there were 3 files, around 1.5GB each, two of them were copied OK, but system freezed on the 3rd one, while copying was about 50%. After rebooting, the destination files was 0 bytes in size. I then copied only this one file, and it was OK. I also noticed, that while copying files, copying is done in big chunks, for example, this 1.5GB file (when copying was done OK), was read to ~55%, then cache (?) was flushed, and data written (much longer process than reading), then reading up to 80%, then writting, and then reading to 100% and writting again. So my wild guess, is something wrong with writting, because on the last freeze I was actually watching the progress, and system frozen at point when the progress bar stopped for a longer time -- and this is moment of writting. Another (unrelated) story is, that those chunks are a bit strange, I have 16GB memory, so it should be possible to read entire file in one pass. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

"After" means exactly this -- _after_ -- MC window with progress disappeared, and seconds later, entire system froze. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Jiri, since I want to keep freezes to minimum I should use bare cp for copying, not MC, is this correct?

No, I want to see the crash. So use mc.

I just tried to run klogconsole -l 8 -r 0 but no new console was shown, so by "there" you meant the original console? I hope I can do this within Konsole.

No, you have to switch to a real console by ctrl-alt-f1, then run klogconsole -l 8 -r 0 and then mc and copy the files. After it hangs, on the console there should appear some messages if the freeze is not a hard lock. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

so I believe this second part is tail of previous message later overwritten by MC

Ok, so set up one console for logging (the same as the last time) but run mc in another console (e.g. in some X terminal). Then switch back to the logging console and wait if it crashes again. After the crash you should see it clearly. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Right. There are only martian-source packets reported.

For the record, I executed klogconsole in console 2, I ran copying on console 4, I switched back to console 2. ATM SSH was active and I could work remotely.
