Again, this is from memory, but I think somebody noticed that copying a
single very large file brought a system to its knees until the copy
finished, and the whole thing spiralled from there. Probably

Thanks.

How will that make any difference? 2.6.18-348 SOUNDS like an ancient (in
linux terms) kernel. Are you on RedHat support?
This is a problem with the linux kernel that was addressed recently,
iirc. Large amou

Looking for some ideas on how to keep Linux from becoming largely unresponsive
when creating large files. What happens is as the new file is being created
the I/O buffer cache quickly fills up with dirty buffers. Until the kernel can
flush these out to disk there is no avail buffers for I/O op
