DIAGNOSTIC ANALYSIS:
--------------------
strings command run against the core file shows some type of aq operations
occurring:

Unable to match with any known bugs - the errors seem very generic.
The trace files do not report currently executing sql, so we are unable
to determine what exactly is running when these errors occur.

建议：
1.
再次执行该procedure ，确认可以重现该 7445  错误，若不能则继续观察或者忽略该问题

begin
  -- Call the procedure
  pg_ra_cut_userrscchange.selectuserlist(in_area_id => :in_area_id,
                                       in_tml_id => :in_tml_id,
                                       in_device_id => :in_device_id,
                                       in_equipment_list => :in_equipment_list,
                                       in_device_spec => :in_device_spec,

end;

2. 是否apply了 10.2.0.4.3的PSU ，考虑升级到 10.2.0.5.7
