That's a read-only operation too (just like svnadmin dump), so should
be perfectly safe. BTW, both 'svnadmin dump' and 'svnadmin verify'
should run without problems on a busy repository (it doens't interfere
with commits and other write or read operations that happen in
parellel).

Hm, the fact that you *were* able to dump it in full (I guess by
splitting it up in chunks, as was suggested by Nico) indicates that
it's probably not a corruption in your source repository. The fact
that it works by dumping in chunks, but not in one giant dump, points
to a resource problem for creating or storing the giant dump.

Here too I would guess you hit some system limit (RAM / swap space,
disk, maybe open file descriptors, ...). Perhaps you can split the
load process in even more steps, by specifying even smaller revision
ranges (but still using the dump files you created earlier). See
'svnadmin help load':

[[[
...
If --revision is specified, limit the loaded revisions to only those
in the dump stream whose revision numbers match the specified range.
]]]
