@paul:

google is your friend... ;)

FWIW,

> "INFO: Waiting for N instance(s) to be deallocated" where N is some large number like
>100. 

this is a tomcat specific message. i don't know whether it's actually caused by a jackrabbit
problem
in your case, but google returns lots of hits, e.g.

the best"

> It seems that it happens not all the time. The error occurs since we use Jackrabbit 1.6.0.
We do not get the error with previous versions. It seems that we only get the error when trying
to copy nodes that were created with Jackrabbit 1.4 and copied with Jackrabbit 1.6.
