Hotcopy failure

I have a repository on fedora core 4 with svn 1.2.1 and Berk 4.3. This
db was created in the svn 0.6-0.7 time frame and hasn't been through a
dump/load cycle since. I am using http and svnserve to access my
repository. My repository I about 6.4 GB in size.

For the past two days when I try to hotcopy my repository (even when I
do not have any service accessing it) I get this error:
        svnadmin: DB_RUNRECOVERY: Fatal error, run database recovery
        svnadmin: bdb: Logging region out of memory; you may need to
increase its size
        svnadmin: bdb: Recovery function for LSN 18565 238216 failed
        svnadmin: bdb: PANIC: Cannot allocate memory
        svnadmin: bdb: PANIC: fatal region error detected; run recovery

I am planning to do a dump/reload soon to allow me to go up to svn123,
because I cannot without doing so for some reason. This being said, I'd
like to be able to do this at my leisure. The fact that I cannot backup
has my quite worried about the state of my db.

When I run recover it finishes quickly and says there are no errors....
Could it be that my DB_CONFIG should be altered? I have 2GB of ram on
the box, so I have no problem upping any values.

Please let me know if anyone has any clues or suggestions. Thanks...

# Increase the size of the in-memory log buffer from the default
# of 32 Kbytes to 256 Kbytes. Decrease the log file size from
# 10 Mbytes to 1 Mbyte. This will help reduce the amount of disk
# space required for hot backups. The size of the log file must be
# at least four times the size of the in-memory log buffer.
#
# Note: Decreasing the in-memory buffer size below 256 Kbytes
# will hurt commit performance. For details, see this post from
