Hello,
We are using phabricator for about 6 months now and everything went great. We used several projects with git.
We then wanted to import other teams SVN projects.

And then issues started.

One of them was a 80000+ commits project, and the /var space was not big enough. We extended the space but it was still very slow to import and we finally removed the project. But new commits were still in "Importing..." phase, something was stucked.
We ended up with a lot of failing task in daemons log about non existing commits, by increasing a bit phd.taskmasters we cleaned them up and now they are gone. All other repositories commits are visible.

But still, now on daemon page we have a lot of :

Fatal error: Call to a member function getTableName() on a non-object in /srv/www/phabricator/phabricator/src/applications/diffusion/query/pathchange/DiffusionPathChangeQuery.php on line 66

And some SVN commits are in "Importing..." phase even if the repository is marked as imported.

Leased tasks PhabricatorRepositoryCommitOwnersWorker don't disappear and we still have 15000+ queued tasks.
How can we get rid of theses failing tasks ?

thanks
