shrug-l: Sporadic Empty Geometry Errors

[Johnson, Jay]

We are editing a geometric network stored in SDE. We get intermittent
"operation attempted on empty geometry" errors. The odd facet of this error
is that one user may experience the error while attempting to trim a
specific line; another user (from another physical location) can go to the
same feature and perform the trim operation successfully.  This would seem
to indicate to me that the "empty geometry" error is not the root cause; if
there really was a problem with the geometry it shouldn't be possible for
ANY user to successfully perform the edits.  Any thoughts on possible causes
for such an inconsistent behavior?  Any way to determine if this is caused
by a database issue, an Oracle/SDE issue, or a network issue?  Thanks.
