Re: Any known leaks in ExtFile and OpenFlow?
Hi all, One of my Zope (2.8.4 on Python 2.4.2, SLES9) sites constantly hits the memory limit. It makes heavy use of two products - ExtFile (1.5.0) and OpenFlow (1.1.0). ExtFile class (of ExtFile) and workitem class (of OpenFlow) are leading the refcount list with a not-constant but overall increasing numbers of references. Refcounts for both reach numbers that are incomparably higher than the numbers of their instances in ZoDB. I wanted to ask if there are known leaks in these products before going into (painful) hunting and debugging leaks in my own code. Thanks!
As (a co-author) of OpenFlow there is no known leak in that product... we will try to provide support in order to see what are the problems. Feel free to contact me directy. Regards Marco On 6/4/06, Michael Vartanyan <pycry@doli.biz> wrote:

I don't know if this is related or not, but python2.4.x is not supported on Zope 2.8.x. But chasing down issues like this will be definitely be harded while not running a supported base configuration. - Rocky -- Rocky Burt ServerZen Software -- http://www.serverzen.com News About The Server (blog) -- http://www.serverzen.net
Thanks Rocky, I knew about that. Actually, with Python 2.3.5 it behaves exactly the same... Rocky Burt wrote:

I am not aware of leaks in ExtFile but am certainly interested should you be able to point out some. ;-) Stefan On 4. Jun 2006, at 11:59, Michael Vartanyan wrote:
