On what version of Relativity are you experiencing this issue?

Are you encountering this issue with an indexed, relative, or sequential file?

If this is an indexed file, what is the file version of the file that is encountering this error?  What is the configured LOCK LIMIT for this file?  You can determine an index file's version, and configured LOCK LIMIT, with the The Map Indexed File (rmmapinx) utility.

A 94,67 error indicates that an attempt was made to open a file that is too large for this system, however, SCO OpenServer 6 should support large files.  Therefore, there must be some other element in the environment that is causing this condition.  Once we have some additional information about your environment, then, we should be able to determine what is causing this issue.
