May I ask how is that related to ReiserFS?  Seems like a rather generic Linux problem to me, maybe you could try the Red Hat forums, mailing lists or IRC channels.

The system originally was running ext3 until we flattened it and 
reinstalled RedHat with the reiser file system.  I have other systems 
not running reiser which perform just fine.  The problem seems to be 
pointed at the filesystem

I had presumed there was something I needed to tweak there.

Yes network connectivity with the box is available.  The disk space is 
slowly dropping.  We're running 2.4.9 -e38 on the RedHat Advanced 
Server.  Memory seemed to be fine on the system.  Nothing unusually 
there (1.5 Gigs of ram on the server).

I'm recycling the power on the box.  Reboot and init 6 seem to run 
however it's not bringing down the box.  Very strange problem :-)

Thx

Can't kill a process

[Frank Carreiro]

I have a rather intense process that has been running since last night.  
I wanted to kill it since it's eating up my cpu however kill and kill -9 
don't seem to be doing the trick.

I'm running the reiser 3.6.25 file system on a RedHat Advanced Server 
(2.1) with 2.4.9-3.38smp kernel.

It's simply counting the time away as it copies files to disk.  I've 
reniced it to 15.  It's also on a raid 5 array and I've modified my 
min/max speed to 10/50.  Performance has improved however the process is 
still running. 

Thoughts?

thx
