[Zope] Unstable Zope: Out of Memory problems

[Paulo Eduardo Neves]

Two weeks ago I started to have stability problems with Zope. I'm=20
getting a lot of random "Out of Memory" errors. I'm using Zope in this=20
server for more than an year, I don't know what's happening now. Sure I=20
wouldn't won an oldest running Zope context before, but now it's=20
restarting each 20min! Zope server starts fine with some 14M and=20
crashes when approaches 20M.

I'm trying to minimize the amount of memory that Zope uses. I did:
  1. put a lower amount of cache in the Control Panel > Database=20
Management > Cache Parameters tab
  2. removed full sections of my site, now my Data.fs has just 10M
  3. lowered the number of threads, it's running with the default four.

Is there anything more I can to run Zope with less memory?

I've also tried to debug it, using the debug tab, but everything looks=20
fine. The top object has less than 450 refcounts. Can anyone help me to=20
debug it?

Maybe the problem is with my server, I'm with Zope Server behind Apache=20
(with mod_gzip) via mod_proxy in a FreeBSD 4. It's a virtual private=20
server of ViaVerio (know before as IServer). The support said they=20
allocate me just 14M of memory for each process. It worked fine for=20
more than a year. I've found an old zopista that uses the same server=20
and also had out of memory errors:

Would my only solution be to change my hosting company? Do other=20
zopistas have any suggestion of hosting plans that give "almost root"=20
power for less than US$100? Besides IServer, I've just found this one=20
from ForSite: http://www.forsite.com/vds.htm
It is a little off-topic, please answer me privately about the servers=20
that I'll post a summary to the list.

regards and thanks in advance for any help,
Desperate Paulo
