Hi,
This means that you have an issue with your rules.
The tool is very picky with accepting only SVN revisions that can be made into git commits.

[prinz3nroll3]

@tnyblom thanks a lot for your answer.
i changed the parameter to:
--svn-ignore
--empty-dirs
and now the conversion did not crash with a log, like above.

now the conversion from revision 2210 takes a ver long time.
i get the message Exporting revision 2210..... with a lot of points and after some hours, the machine is under heavy load, i get the error message killed :-(

[eeijlar]

Is there a dud commit at revision 2210? I had a similar problem where someone had checked in a 50GB SQL file and it was still converting after 18 hours. I had to repair SVN to fix the issue.

[prinz3nroll3]

Change the rule works, i get now no empty patch crash.

How did you repair the database?
