We need to do some more changes in this. The concept is first pool alloc and then memory alloc in the pool, so the memory has to be freed if the memory is allocated in the pool and irrespective of memory allocated or not the pool has to be destroyed if it is created. We will work internally and provide a complete patch. Thanks Sathya -----Original Message----- From: Martin K.
