Full error message is ....
ORA-04031: unable to allocate 4032 bytes of shared memory ("large pool","unknown
object","session heap","frame segment"))
I am already monitoing both shared pool and large pool free memory every 30 minutes
and there is no issue with that. As I mentioned below Oracle is not displaying any
error message or trace file.

Well, you neet to check the full error, because otherwise there's no
way to tell if you are running low on shared or large pool.
The view that shows space usage in both places in v$sgastat. I
suggest you start looking there. Maybe your third-party application
doesn't use bind variables and is bloating the shared pool. You could
verify this by observing that the sqlarea component of the shared pool
is very large as seen in v$sgastat. If this is the case then you might
consider testing with cursor_sharing=force.
You could also count different versions of similar SQL from the
application by grouping sql_text in v$sqlarea by the first 30
characters or so. This assumes your problem is shared pool sqlarea
bloat. You could just be runnning out of space for MTS session heaps
in the large pool. You have to look at v$sgastat first.
