Deployment Manager hangs during execution

Question

We use OWB 10.1.0.4 with 10G release 2 DB. Everything was working, until recently - the deployment manager hangs while trying to execute any mapping. Deployment of mappings however works well. Also executing the mapping from SQL*Plus works well.
We are not aware of any changes done recently. We tried re-registering all the locations and redeploying all the mappings as well. Execution of mappings leads to core dumps
Here is an example of the core dump and what OWB is trying to, it happens even before the parameter page is displayed which prompts to enter the execution mode, bulk size etc:
RA-07445: exception encountered: core dump [kkosbn()+236] [SIGSEGV] [Address not mapped to object] [0x000000070] [] [] Current SQL statement for this session:
select
parameter_name,
parameter_type,
parameter_kind,
parameter_mode,
is_fixed,
is_required,
parameter_uoid,
default_value
from
wb_rtv_task_parameters
where
task_id = :1
and
(parameter_mode = :2 or
parameter_mode = :3 or
parameter_mode = :4 )
and
(parameter_kind = :5 or
parameter_kind = :6 )
order by
parameter_mode, parameter_name

Hi,
There are atleast two possibilities :
1. If core dump is happening over and over again, then take the trace file and report to Oracle technical support. I had one such case of core dumps where it was later found out to be a oracle bug and a patch had to be applied.
2. If the mapping hangs then there is a high possibility of version mismatch between the location and the actual database. Try to re-regsiter all the locations and deploy all the mappings.
All the best
