temporarily can't create new locks

Hi I have a SVN + Apache setup running on FreeBSD :
# uname -v
FreeBSD 8.1-RELEASE #0: Fri Aug  6 09:37:33 CEST 2010
# svn --version
svn, version 1.6.16 (r1073529)
    compiled Apr 13 2011, 09:43:52
# httpd -v
Server version: Apache/2.2.15 (FreeBSD)
Server built:   Jul 23 2010 18:16:05

Today users had problems with locks that frozen the repo. TortoiseSVN 
reported the following error :
Can't parse lock/entries hashfile 
'/var/db/svn/repos/agot/db/locks/328/328675b94c4bb4aa73c5554051d076d2'

In the Apache error log file I have the following :
[Fri May 27 10:05:50 2011] [error] [client 10.1.8.180] The locks could 
not be queried for verification against a possible "If:" header.  [500, #0]
[Fri May 27 10:05:50 2011] [error] [client 10.1.8.180] Failed to check 
path for a lock.  [500, #200002]
[Fri May 27 10:05:50 2011] [error] [client 10.1.8.180] Can't parse 
lock/entries hashfile 
'/var/db/svn/repos/agot/db/locks/328/328675b94c4bb4aa73c5554051d076d2'  
[500, #200002]

I also have fails to create new locks :
[Fri May 27 09:36:16 2011] [error] [client 10.1.8.144] Failed to create 
new lock.  [500, #200002]
[Fri May 27 09:36:16 2011] [error] [client 10.1.8.144] Can't parse 
lock/entries hashfile 
'/var/db/svn/repos/agot/db/locks/328/328675b94c4bb4aa73c5554051d076d2'  
[500, #200002]

If I did an "svnadmin lslocks [path]", the command returns something 
like "the file is malformed".
Un fortunately I didn't copy the exact message.

This happened for various lock paths. I tried to move the files in the 
repo 
("/var/db/svn/repos/agot/db/locks/328/328675b94c4bb4aa73c5554051d076d2") 
to see if it works.
The repo was usable again, but locks were still an issue.

I tried to reproduce the problem on a test repository, no problem. I 
asked the users who got problem locking files to try on the test repo 
and on the production repo.
Everything get fine and I was unable to reproduce the problem.

Does anyone have an explanation about this issue ?

I forgot to say that the files are empty(I did not deleted them), the 
permissions are correct (640, www:www)

What is the correct way to resolve this kind of locks problem if the 
svnadmin command doesn't want to remove locks either ?

"Don't do that."

The locks/ directory has invariants that you may violate if you move
files randomly under it.
