Error "ORA-39029: worker 1 with process name "DW01" prematurely terminated"

Question

Hi,
I get this error during an import from my production database schemas into my development schemas:
Processing object type SCHEMA_EXPORT/TABLE/CONSTRAINT/REF_CONSTRAINT
Processing object type SCHEMA_EXPORT/TABLE/TRIGGER
Processing object type SCHEMA_EXPORT/TABLE/INDEX/DOMAIN_INDEX/INDEX
Processing object type SCHEMA_EXPORT/MATERIALIZED_VIEW
ORA-39014: One or more workers have prematurely exited.
ORA-39029: worker 1 with process name "DW01" prematurely terminated
ORA-31672: Message 31672 not found; No message file for product=RDBMS, facility=ORA; arguments: [DW01]
Job "SYS"."SYS_IMPORT_FULL_01" stopped due to fatal error at 12:57:47
ORA-39014: One or more workers have prematurely exited.
This is my parfile:
PARALLEL=1
remap_SCHEMA=xxx:xxx
remap_tablespace=yyy:yyy
DUMPFILE=file.dmp
LOGFILE=imp_file.log
DIRECTORY=dddd
TRANSFORM=oid:n
I try to import with sys and system user.
I can't find anything about this error.

In the alter there was an ORA-00600
Errors in file /home/oracle/oracle/admin/siasvil/bdump/siasvil_dw01_32480.trc:
ORA-00600: internal error code, arguments: [kkqfca:invalid input], [], [], [], [], [], [], []

Errors in file /home/oracle/oracle/admin/siasvil/bdump/siasvil_dw01_32480.trc:
ORA-00600: internal error code, arguments: [kkqfca:invalid input], [], [], [], [], [], [], []
And in the trace something about a select:
ORA-00600: internal error code, arguments: [kkqfca:invalid input], [], [], [], [], [], [], []
Current SQL statement for this session:
select
e.id_nodo_alb_class||'/'||SEQ_AUX KEY_CODE, ID_AUX_ENUM ID_KEY_VAL, NAME_VALUE
DESC_KEY_VAL,
DS_VALUE DESC_LONG_KEY_VAL, CD_TIPO, SEQ_AUX, n.ID_NODO_ALB_CLASS ID_NODO, n.ds_nodo
from ri01_aux_enum e, ri01_nodi_alb_class n
where e.id_nodo_alb_class=n.id_nodo_alb_class(+)
Now I'm execute the impor command with CONTEN=METADATA_ONLY
I will see if it will works.
