Extracting large tar files via SSH causes shell to crash (Oops)
Last modified: 2005-10-31 17:00:50 EST
Description of problem: When extracting large tar files (approximately 800MB
and higher), causes the linux kernel to produce an Oops and crash the shell.
The Oops can occur up to 2-3 hours after the initial extraction of the tar file.
Version-Release number of selected component (if applicable):
How reproducible: Using a ssh shell, log into the linux server and extract a
large tar file (approximately 800MB or higher). The extract syntax is: tar -
xvf file.tar. If the tar file is incomplete, the shell will crash
immediately. Otherwise, the shell seems to be unable to recover from the
extraction process and cause an Oops in the kernel up to 2-3 hours later. It
appears that the background processes become corrupt after heavy I/O activity.
Steps to Reproduce:
1. Copy large tar file to system (800MB or higher).
2. Log into machine using a SSH shell and type: tar -xvf filename.tar (to
3. kernel will cause an Oops and the shell will crash up to 2-3 hours later.
Note: The kernal will Oops and crash immediately if the large tar file is
corrupt or unfinished.
It works for me on FC2.
But it might be a kernel bug or hw problem, don't u thing so?
