[postgis-users] Performance and memory problems

[Andrea Aime]

As strk suggested, removing the pfree(r) line makes the overlay go on
but the whole thing goes out of memory after reaching the 12000th
result geometry (and consider that the baby has 21000 shared buffers,
which is almost 160MB of shared memory. So, it seems that sometimes
the above line incurs in a double free problem, but maybe the out
of memory I get is due to non freed memory during the overlay ...

Best regards
