Thanks to everybody for the feedback. As I said before, the problem is that using PLI verbs program sometimes runs out of memory. At every FREE I flag the block with a timestamp and, at dump time, lots of blocks logically freed are physically in the dump. So, in theory I've free blocks to reuse (as you said PLI use heap or similar to alloc bigger blocks to use at purpose) but I run out of memory.
I've to be very sure of my finding. Best regards.
