Hi All,
We're having serious
problems with performance running Silva CMS on Zope 2.7.8-final, python 2.3.5,
linux2 set up on a machine with 2.5GB RAM. There are currently only about 65
users and around 2000 documents in the CMS but it seems to run for a week, then
the RAM fills up and crashes so we have to restart the server manually.
The Zope logs aren't much
help as I enquired on the Zope list and their response was we need more RAM.
But surely 2.5GB is enough.
I've also checked
Control_Panel/DebugInfo for any refcounts with significant jumps and
Products.Silva.Image.Image seems to be the culprit:
11.32am 11.36am
Products.Silva.Image.Image 56203
58153 +1950
Acquisition.ImplicitAcquirerWrapper
44825 45151 +326
So we've tried to figure out
which kind of request triggers these refcount jumps by creating a separate
instance with a very small ZODB Cache (so it gets filled up soon), and clicked
around a little, watching the refcounts but we cannot seem to replicate it.
So basically this is a plea
for help from an expert Zope debugger who can assist us in finding the source
of the problem so we can resolve it. Or alternatively someone who can give us a
set of instructions that we can follow that will enable us to locate the
problem, I've googled it and there are no clear answers.
FYI we have the following
products installed on our Zope instance.
