[reiser4] Bug-report

[Francesco Biscani <frbiscani@jumpy.it>]

Hi,

I'm testing reiser4 on my / partition. So far I haven't had a single problem. 
However today I installed the vsftpd ftp server and I had a system freeze. A 
friend of mine was d/l-ing some files from my PC.

The first thing that alarmed me was that I saw on KDE's system monitor that my 
CPU utilization rate, at a certain point, suddenly began to hit 100% 
constantly. "top" revealed that the ftp server was eating all my cpu cycles. 
This lasted for about a minute or slightly less. I don't think this is 
normal, I've never seen this happening with proftpd. I was inclined to 
consider this as a bug of vsftpd's. 

But after about half an hour my X session began to be very sluggish. I could 
not fire up a terminal to see what was going on, but KDE's system monitor 
showed that all CPU power was being eaten by the "system" (I mean that this 
time the CPU was hogged by some kernel activity, not user-space). I had no 
choice but to reset.

Fortunately I found no errors on the fs after the "cold" reboot.

But the system log had not been written during the freeze, so there are not 
many clues on what has happened :-(

I hope this will be useful.. Some of my specs, follow. Let me know if you need 
more.

"Standard" (i.e. default) reiser4 options in kernel .config. No 4k-stacks, 
reiser4 auto-snapshot of 2th July.
