Zopists,
I am spoiled. I have a large server and until now I have never really
monitored memory usage. But I noticed things slowing down a great deal
and was curious. Swapping.
Machine:
RH 6.1
2.2.12-smp
Dual Xenon
1 gig memory
Zope install:
Zope 2.1 Binary
ZODB pure.
No DA's
Home grown ZC
Jason,
Try /Control_Panel/manage_debug ... it will tell you exactly which
kinds of objects are eating memory. Take a "snapshot" then refresh the
page after a couple of minutes, and the table should list at the top
the name of the class that's taking up more than its fair share.

It's so weird. Even though there is really no one on it that memory is
just flying out the window.

It doesn't look like the number of objects is dropping like it should when
it's set at 3 seconds. After 30 min I'm still at

After being up for about a half-hour my objects reading are:
Total number of objects in the database 300280

That's a big relief. Okay, now we know that this isn't a memory leak,
it's only related t

Well, I reduced the 'target size' from 20,000 object down to 1000, and the
memory seems to be climbing.

Since this is a very heavily used Zope install, I am getting trashed faster
than you can say 'leakage'.
