I have a crucible instance running over a single SVN repo. It has historically worked, recently it has started failing to index. I have tried reducing the number of revisions to even the single most recent entry and it is failing to index. It scans all revisions easily, but sticks at the start of the idex process.
I have tried index, full reindex, manually deleting the whole index and I get the same issues. It appears to just get stuck and eventually Java just uses all the memory on the box until no-one can get in at all.
