Description of problem:
When copying, unzipping, untaring large files (1.8GB) there is intermittent
data corruption. The file sizes are the same but when diff or cmp is run there
are 4 to 8 bytes of corrupt data. The problem was reproducible on 3 separate
machines, and rebooting the servers fixed the problem temporarily. Weâve run
hardware diags on all 3 machines with no failures. The servers are:
Compaq DL380s 6GB RAM
2 Intel Xeon 2.8GHz processors
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. cp 2-gig-file 2-gig-file.new
2. cmp -l 2-gig-file 2-gig-file.new
Actual Results: Displayed several lines of differences.
Expected Results: Should have returned nothing. I.e. no difference in files.
All machines have the CD versions of all RPMS. Only the Enterprise kerel has
been upgraded to e.18
Upgrading to the e.27 kernel seems to have fixed our problem.
