After applying maintenance level 9 you need at least to update libc.

See this APAR :

Customers are encouraged to move to AIX 4.3.3 Maintenance level 09 but
there is a LARGE performance bug due to a memory leak in libc = just about
every process in AIX. Make sure the bos.rte.libc.4.3.3.77  software is
installed for ML09


      after AIX 433_09 aix_ml then this apar for memory leak issue.
