| Logged In: YES user_id=31435 Please identify the Python version and OS+compiler+C library in use. The process size remains steady for me under current CVS Python on Win2K w/ MSVC6. A true leak is possible but unlikely. More likely is that your platform C malloc()/free() decide not to return memory to the OS. If so, that's outside of Python's control |

| Logged In: YES user_id=31435 Again, please identify the Python version and OS+compiler+C library in use. I'm not arguing with you, I'm trying to help . Since I don't see any evidence of anything like I leak when I try it (memory usage didn't increase *at all* when I tried it) , the answer to why you see it must lie in something you're using that I'm not -- only you can tell us what that might be. I already told you the Python version, OS and C compiler/library version I used. |

| Logged In: YES user_id=91277 We use HP UX 11 and BSD 4.7 but what were the origial build compilers and libraries will have to wait till Monday - when I will be back at work and have access to the NYSE trading floor systems. I am chasing some memory leak that occurred when we moved from python 1.5.2 to 2.2 I don't think this is it, but... Thanks for your quick response. |

| Logged In: YES user_id=33168 Was the python version 2.2 or 2.2.2? If you are using 2.2, you should probably try to upgrade to 2.2.2 since there have been many bug fixes. |

| Logged In: YES user_id=91277 My apologies: gc was compiled disabled, and probably other things were non standard. On rebuilding python the problem went. Thanos |
