Which exact error messages do you get?
If you get ORA-4031's, then given the fact you actually have free memory in
shared pool (as stated by shared pool free memory statistic), you might have
too many shared pool subpools used.
What does the following query show?
select count(*) from x$kghlu where kghlushrpool > 0 ;
If it shows more than 1 then your shared pool has been partitioned into
several subpools and you might be able to fix the issue by setting
_kghdsidx_count to 1 (or lower value from your current one) if it's ok with
Oracle support..
