svn dumps core on commit of move operation with lots of files

Hi,

I'm currently running a experimental require generation of more than
50000 files, each files are less than few K bytes. I want to keep
these on subversion.

OS and Machine: FreeBSD 5.4R, Xeon 3.8G x 4, SMP Kernel, 4G memory
                       Generic SMP kernel + process data limit = 2G option

subversion: version 1.3.0 (r17949) with ra_dav, ra_svn, ra_locl
            running via apache 2.0.55
    (everything installed via latest FreeBSD ports, built from src)

Firstly, I created these files in a directory.

# Yes, I'm stupid enough. I know..

Then try to comit about 10% of files. It takes long time, thus I
decided to create these files in subdirectories (about 1800, at this
moment)

I have to move already created files onto subdirectories according to
some rule. I created a batch script to run "svn mv" each files to
directory. Finally, I ran commit.

What happend was, svn process keep growing and hit resource limit
(512M first) then dumps core. I raised its limit to 2G, but it *STILL*
dumps core.

# I did svn cleanup and some of .svn/log file removal by hand, to
# continue.

Is there any known reason?

attached please find stacktrace
