Subversion Exception during cleanup

 I encountered the following exceptions (see below) in the mid of
SVN-Cleanup.

What I was doing:
- SVN-merge via TortoiseSVN, stopped with Error due to SVN-lock
  (small local changes separate from merged locations)
- SVN cleanup via TortoiseSVN on locked folder -> exception
- press [OK] -> next exception
- press [OK]
- trying cleanup again -> "Cleanup has successfully processed the following
paths: ..."

Best wishes

Subversion Exception!
---------------------------
Subversion encountered a serious problem.
Please take the time to report this on the Subversion mailing list
with as much information as possible about what
you were trying to do.
But please first search the mailing list archives for the error message
to avoid reporting the same problem repeatedly.
You can find the mailing list archives at
http://subversion.apache.org/mailing-lists.html

Subversion reported the following

Cleanup failed to process the following paths:
E:\Projekte\ORS_Applications\ORSOFT_7_5_1
sqlite[S5]: database is locked, executing statement 'PRAGMA
 case_sensitive_like=1;PRAGMA synchronous=OFF;PRAGMA
 recursive_triggers=ON;PRAGMA foreign_keys=OFF;PRAGMA locking_mode =
 NORMAL;PRAGMA journal_mode = TRUNCATE;'
Another process is blocking the working copy database, or the underlying
filesystem does not support file locking; if the working copy is on a
network filesystem, make sure file locking has been enabled on the file
server.

OK
