Unable to write trace files in Background dump destination in oracle 10g

Question

Hi All,
OS version : RHEL 5.7
DB version : 10.2.0.4
cluster : 2 node RAC database
Today I faced a strange behaviour for one of our production database. Its a 2-node rac database. On the first node there is no auto generation of trace files in the BAckground dump destination. I am able to see trace files of second in its background dump dest. But the strange behaviour occurs on the first node. I see only Alert log file in the background dump dest . Inspite of getting an error which shows trace file generated but no file occurs in the bdump. The following is the error but physically there no trace file generated:
Errors in file /oracle/db/admin/<sid>/bdump/<sid>j0011558.trc:
ORA-12012: error on auto execute of job 94377
ORA-12008: error in materialized view refresh pathCan anyone have any idea for this strange behaviour. There are no maintenance script for removal of trace files.
Regards,
Imran Khan

ORA-00980:synonym translation is no longer valid
Cause:The synonym used is based on a table, view, or synonym that no longer exists.
Action:Replace the synonym with the name of the object it references or re-create the synonym so that it refers to a valid table, view, or synonym.
Check the following :
From User Number 1 : Osama1
create table osama_table as select empname from scott.emp;
create public synonym osama_tbl for osama_table ;
grant select on osama_tbl  to user_b;
From User Number 2 : Osama2
select 1 from osama_tbl;
SMITH
ALLEN
JONES
MARTIN
From User Number 1 : Osama1
drop table osama_table;
From User Number 2  : Osama2
select 1 from  osama_tbl;
ORA-00980: synonym translation is no longer valid
