[Exist-open] Data Loss

[Leigh W. <le...@le...>]

Hello,

I've been using this set of data for a couple of weeks now and today I had a
connection hang while talking to the database using XQuery.  So I quit the
programme, and restarted; had the same problem.  So I shutdown the program and
then eXist and now I cannot access a collection.  I tried to backup the
collection but got the exception at the bottom.  No amount of coercing will get
me my data back.  Any ideas how I managed to lose data?

Leigh..
