Hi Manu,
it seems that your application missed a lot of things in the
initialization sequence. For example, it missed calling pj_init()
and pj_caching_pool_init(). Please refer to the sample codes for
some examples.
As the name implies, pool factory is used to create and destroy
pools. Among other things, it contains memory management policies
that application can tweak so that all pools would behave according
to what application wants.
Pool factory does not allocate memory on it self, as this will be
done when the pool is created. But it does specify the policy on how
the pool can allocate memory blocks from the system.
regards,
