Are you closing the postgres database to do a backup ?

Subject: [GE users] DBWriter dies nightly

I like DBWriter, however I haven't been able to get it to work for more 
than a night. I get this out of dbwriter.log:

25/07/2007

flushing the output - Exception: java.net.SocketException: Broken pipe

Stack Trace:
   <<tons of stuff here I'll send if necessary>>

Even if the database goes away, isn't the whole idea of DBWriter to stay

alive while the DB is down and write stuff later? Anyone else having 
this problem?
