I'd like to upgrade
bug 1950 to critical.
Is there an easy way
to do this?

Thats not unreasonable for the working set of zope.
Hi all,
I have isolated the memory leak problem on a naked 2.3.3 Zope.
I have on ZPsycopgDA and two SQL Methods, one SQL Method contains
DTML-IFs and DTML-ELSEs and REQUEST.sets
the other SQL Method contains the rendered query of the first, this
means there is pure sql in it.
Both methods cache t

That class is used to glue together acquisition content chains. Being
top of the list indicates that you have been leaking an acquisition
context chain.

Maybe... depends on your level of Zope Zen. It's hard to tell which classes
should and should not have high refcounts. For example, in your sample
output, I

Hi all,
i have a little problem with my production server.
The memory usage of the zope processes running on this server are
growing up
100K a day upto 1MB a day.
How can i track down the problem.
Zope is 2.3.3
Python is 1.5.2
OS is RedHat Immunix 6.2
Hope somebody could help...
Thanks,

Just occured to me if Im leaking REQUEST it would be nice to see exactly
which requests im leaking. But is that really covered by the -M logger, if a
request fails to be closed in there does that really translate to a leaked
request? I had a look in the code and it wasn't obvious to me

This turns out to be a memory leak in ParsedXML. DOM references
created during a parse aren't released.
We hope to have a new release very soon that fixes this.
Restarting Zope is a temporary workaround - DOM refs retrieved from
the DB aren't being leaked.

any chance that this is the same problem that andy is running into (read his
