After "quit" the engine quits and any allocated memory will be released by the OS no matter what. However, I am reasonably sure that the engine itself releases all memory allocated by the probing code before it actually quits. (OK, that is not part of the interface/tbcore.c code, but that is not a full engine anyway. I am talking about Cfish and Stockfish.)
After "stop" no memory is deallocated because the engine will likely search another position.
The "more and more memory" consumption is not caused by Pairsdata allocations but by more and more of the TB files getting swapped into shared memory (shared with any other engines also accessing the TBs).

Setting the TB path (SyzygyPath) to "" releases all memory. I think that is part of the interface/* code but I could be mistaken.

Indeed setting the SyzygyPath to "" before closing the engine seems to free the allocated PairsData. I will use that. Thanks.
