Réf. : Re: SPI memory managment issue

From
bsimon@loxane.com
Date:

after investigation, I have to reformulate :

The actual memory is freed after each call of spi_finish, which is cool. However the global amount of virtual memory used by the process does not decrease until the last spi_finish. I get :

ERROR:  out of memory
DETAIL:  Failed on request of size 10.

...unless I set the virtual memory up to more than 2 gigs. Why isn't it freed ?

My config is :
 windows 2000, P3, 256 Mo ram.

No, spi_finish frees memory used in that particular SPI invocation.
What's your evidence for thinking otherwise?
