There might be still a problem with feeds with very large item numbers
and the aggregator - it doesn't handle those feeds very good. Especially
if you already have large amounts of postings for that feed in the
aggregator database.

Woops. You could start it with

pyds-start -f -v

to see what it does when starting up and how far it comes. This will
show you more details on what happens within PyDS.

pyds-start -f -v -e

will even echo all eventlog messages to stdout. That's especially
helpfull if you can't access the eventlog any more.

Every tool has it's own database in ~/.PyDS/var/ - so you can just
delete those databases where you suspect broken content. But tools
usually keep setting and items in their database - so if you remove
aggregator.data, you will lose your subscriptions.

Do you use the backup feature? If yes, you can just set up a new
instance and pull in your backup with pyds-restore.

Other options would include stopping PyDS and just using Metakit and
Python to look at the database files directly. Phil did post some repair
script once, you might find it on his "second post" blog or in the PyCS
mailing list archives (PyCS uses the same database).

If you use Metakit to directly access the data files, you can use the
introspection stuff from Metakit to look at your data and for example
pull out the subscriptions from the data file. I currently don't have
any repair scripts ready, but if somebody builds some tools, send them
in for inclusion in the distribution.
