Unfortunately, kaserver is a service that has been deprecated within
OpenAFS since the release of 1.4.

  http://www.openafs.org/no-more-des.html

As described, in the upcoming 1.6 release kaserver will become an
optional build component and in 1.8 kserver will be off by default.  If
the 1.4 kaserver is unreliable in your environment I would recommend
continuing to use the IBM kaserver on the platforms where it is
supported or you can try the OpenAFS 1.2 kaserver on the platforms where
it is supported.

Another option that you can try is to use the 1.5.74 kaserver.  I
mention this because although there has been no kaserver specific work
over the last five years, the src/kauth directory has not been ignored
by the efforts to prototype all functions and remove all warnings.
However, the kaserver code is plagued with warnings from the DES library
(particularly on 64-bit systems) and no efforts have been made to
correct them.

Migrating to krb5 is the preferred option of the community.

OpenAFS will accept patches to kaserver that fix functionality.  The
challenge is going to be finding someone to identify the bug(s) and
develop and test the patch.  We have not had anyone since the creation
of OpenAFS be interested in spending significant effort on the kaserver
source code.

Did you examine the VLLog log on the VLDB server that is currently the
sync site?
