OEL Linux 5.5 64bit scp copy errors CRC file errors

[whowery]

I have a EOL 5.5 Linux 64 bit VM running on Ubuntu 10.10 When I do a scp of large files 700M+ to the vm, the files have inconsistent CRC checks. The failure is very consistent. Smaller files copy fine.

I've zipped and 7z'd the files to validate the copies, Also have errors. I've created a blank VM from the OEL 5.5 distribution and still have errors. I also see the errors using filezilla from with both a Ubuntu or Windows Host.

Any ideas?

A bit more detail:

Specifically I'm trying to copy Oracle DB11gr2 from my host machine Ubuntu 10.10 to the OEL 5.5 64bit Virtual machine. When the zip files are copied to the Virtual machines the cksum results do not match the source versions.

The Virtual guest has 4 nic cards one Brigded, one NAT, and two HostOnly.

I've tried the following:
copying the files through the HostOnly and Bridged,
scp with -l to slow down the copy, thinking I was having a buffer problem.
split the zip files into smaller pieces (200MB) and will consistently get a cksum error on one piece of the split.
Used FileZilla with throttling
Downloaded the source files and still had cksum errors.
Created a new Guest system with the same results.

A colleague has had the same set of experiences using a Windows 7 host system.

Has anyone had similar problems?
