Thanks for the quick response. It seems indeed that clearcase keeps a
cache of open files, even when they are "logically" closed. The size
of this cache can be set (1800 seems to be the default).

For the time being I will experiment with that setting and see how far
I can go with that....

I'm happy to hear that this will be resolved, and even more happy to
see such a quick response - Thanks a lot!
