Just wondering if anyone else has come across an issue where files
cached in memory appear to become 'corrupted' - for example, on one
workstation, I've just had the issue:
Traceback (most recent call last):
File "/usr/bin/yum", line 4, in ?
File "__init__.py", line 36, in ?
File "config.py", line 34, in ?
File "repos.py", line 29, in ?
File "repoMDObject.py", line 18, in ?
strace'ing the process didn't show up anything obvious
However, I ran a simple process that just grabs memory - which has the
side effect of 'flushing' caches from memory.
After, doing this, yum ran fine ...
I've seen this issue quite a few times with various applications and on
different machines - and flushing the caches in the way fixes the issue ...
OK, it could be a real memory problem, but given the number of times I
see this issue, on machines that are fine otherwise, it makes we wonder
if it could be a cache issue ...
All the machines are running a CentOS4.4 based kernel - (I plan to move
to a CentOS4.6 based kernel when it is out). The kernel is not a vanilla
CentOS4.4 kernel - it includes a few small non-standard patches - but
nothing that touches the VFS layer (AFAIK). The issue occurs on i686 or
x86_64 boxes. All machines have at least 4GB of memory. They also use
the nVidia binary-only module.
Anyone seen issues like this?
