That looks wierd... Has the instance been running for a while when you copied the content of the Cache Parameters tab ? I would have expected many more connections (instead of just 2). Can you give us your zserver-threads value (zope.conf) ? Thanks.

When we started having this problem the box only had 1GB of RAM so we replaced that RAM completely and put in a fresh 4GB of RAM to hopefully get rid of the problem. This box is also running 3 other Zope instances, but the other don't exhibit this problem. This instance has 15 plone site instances in it. The others only have a couple plone sites each.

Hi, Can somebody tell me what I should monkey patch if I need to alter Z2.log logging in order to append a particular request environment value ? I tried but I got lost trying to find PublisherHTTPServer and ZPublisher relationship... Thanks a lot.

Virtual Host Monster
by Nicholas Wieland 12 Sep '05

12 Sep '05

I'm trying to use VHM to rewrite a pair of urls. What I want is to have a "normal" Zope on localhost:8080/, and an instance of a Product on localhost:8080/myProduct. The problem I'm having is that VHM locks me out from the root folder :( My mappings line is: localhost:8080/my_container/VirtualHostRoot/myProduct How do I exclude localhost:8080 to behave normally, as without Virtual Host Monster ? --------------------------------- Yahoo!

Copying "Data.fs" to a different CPU architecture
by Matthew X. Economou 12 Sep '05

12 Sep '05

My Zope server is currently an Alpha running FreeBSD. This computer's CPU is no longer working. I would like to restore my backup copy of Data.fs to a new computer, a PC running FreeBSD. Will this work as a straightforward copy, or will the two platform's differing byte orders (and word sizes) cause problems for me? Best wishes, Matthew -- jsoffron: I'm generally pretty high on national defense... Mr. Bad Example: Careful...it's a gateway policy. Before you know it, you'll be mainlining the hard stuff like trade agreements. jsoffron: Too late...I've been freebasing Nafta all day... Sweet, sweet NAFTA. - As seen on Slashdot

CMFFSContent released
by Jens Vagelpohl 10 Sep '05

10 Sep '05

CMFFSContent - Put CMF content onto the file system If you are looking for a way to manage content on the file system in order to take advantage of better editors, source control systems and other utilities you might be interested in CMFFSContent. CMFFSContent represents a content-ish equivalent to the CMF Skins mechanism. You can register directories that provide filesystem content and file extensions that should be recognized as one of the content types available (FSFile, FSImage, FSDocument) from your code. You can also derive your own FS-based content types and plug them into the machinery. A specific use case would be a "brochure" site that does not offer membership or member-contributed content, but a seldom-changing set of pages that need to be tightly controlled. Case in point: My company page at http://www.zetwork.com, which serves CMFFSContent only. Another suitable candidate would be a site that does have members and member-contributed content, but a specific area for centrally-maintained information, such as a canonical set of documentation pages. Downloads can be found at... http://www.dataflake.org/software/cmffscontent/ ...and bug reports/suggestions/praise/flames are welcome here: http://www.dataflake.org/tracker/ jens

Strange warning after removing products
by Martin Koekenberg 10 Sep '05

10 Sep '05

Hello, A while ago I used the products 'Superlogger' and 'Quicklinks.' I Also removed 'PlacelessTranslationService'. All the products were available in the control_panel. But I still get the following warnings ? 2005-09-10 16:49:05 WARNING ZODB Could not import class 'PlacelessTranslationService' from module 'Products.PlacelessTranslationService.PlacelessTranslationService' 2005-09-10 16:49:05 WARNING ZODB Could not import class 'SuperLogger' from module 'Products.SuperLogger.SuperLogger' 2005-09-10 16:49:05 WARNING ZODB Could not import class 'QuickLinks' from module 'Products.QuickLinks.QuickLinks' Does anybody has a solutiuon for this ? Zope is still running..... but the warning isn't there without a reason. regards, Martin Koekenberg
