Questions:
When checking files (out of and) into cms, large files,
on the order of 6500 blocks, give us a variety of symptoms.
Sometimes, cms says the files don't check in, but they do
and are (show no reservations, and can be checked out),
sometimes cms checks the files in, but saves 0 bytes!,
sometimes we get the check in error, but the next try to
check in works fine.
The question is - with large files (6500 blocks +) are there
problems? With large files, could contention for system resources
cause this flakiness?
Are we the only ones with this problem?
tia.

This appears to be a CMS problem, or a CMS library corruption.
Please check the CMS version, and consider an upgrade. CMS V3.8-2 is
the current release. (CMS V3.8-2 is known to have a problem retrieving
indexed files from a CMS library.)
Larger files -- particularly `binary' files such as Postscript, indexed
files, image files, etc -- are not (locally) stored in CMS libraries as
"delta" file elements... The "delta" of a `binary' file can be as large
or larger than the source file itself -- CMS stores the "delta" in the
library.
Locally, a two-line `stub' -- called a "marker file" -- is stored in the
CMS library, and this stub contains a reference to the actual file. The
storage and retrieval software knows how to recognize and process these
marker files.
If you are running a recent version of CMS, please contact Digital
customer support for assistance.
