The call graph is interesting. What you did not yet tell us, and what
is important in order to interpret the call graph correctly, is how
many rows are present on your setup in ipAddressTable.

As you can see in the source code of netsnmp_binary_array_insert(),
this function adds a new entry at the end of the array and sets the
dirty flag. Setting the dirty flag will make the next call of
netsnmp_binary_array_get() (which is called by
netsnmp_binary_array_insert() to check for duplicate entries) sort the
array. It will probably help to modify netsnmp_binary_array_insert()
such that if the dirty flag is not set upon entry, it does not set the
dirty flag upon exit but instead inserts the new entry at the right
position in the array such that it remains sorted.
