Re: Zope 2.7 - sporadic service hangup

We have for several years run a site without any problems until now. It has over 70.000 registered users, but only about 1.000 logins each day. It is low load on this site. After upgrading the OS (kernel and packages) this spring (around April 2007) we are experiencing problems with our Zope-servers "hanging". It accepts connections, but does not give any response. Nothing is shown in the event.log or access.log (since request never finish). In the trace.log (after turning this on) we can see entries for the last requests that completes and three requests that begins, but never finish (see below). Following requests are not logged in the trace.log file. We experience the same behavior on our production and development system. The production system "hangs" about once every 10-20 days. The development system hangs more often. We are not sure if the "hangs" are related to high load on the systems. I have tried to provoke a "hang" situation by running multiple wgets in tight loops in parallel, but have not managed to produce a hang.

Five: Adapter registry not working?
by Peter Sabaini 04 Jun '07

04 Jun '07

Hi list, I am clearly doing something wrong here. I try to use an Adapter from zope.app.session with an HTTPRequest object, but the Adapterregistry doesnt quite cooperate. Specifically, I try to adapt a HTTPRequest object to zope.app.session.interfaces.IClientId via the Adapter zope.app.session.session.ClientId A short demo: % ./zopectl debug [ ... ] Import stuff: >>> from ZPublisher.HTTPRequest import * >>> from StringIO import StringIO >>> from zope.app.session.session import ClientId >>> from zope.app.session.interfaces import IClientId >>> from zope import component >>> from zope.interface import * Create ourselves a faux request object: >>> env = {'SERVER_NAME': '', 'SERVER_PORT' : ''} >>> request = HTTPRequest(StringIO(), env, None) ClientId implements IClientId: >>> list(implementedBy(ClientId)) [<InterfaceClass zope.app.session.interfaces.IClientId>] It seems ClientId is an Adapter for IRequest: >>> component.adaptedBy(ClientId) (<InterfaceClass zope.publisher.interfaces.IRequest>,) request implements IBrowserRequest, which is a subclass of IRequest: >>> list(providedBy(request)) [<InterfaceClass zope.publisher.interfaces.browser.IBrowserRequest>] >>> issubclass(list(providedBy(request))[0], component.adaptedBy(ClientId) [0]) True ...so I'd expect to get ClientId as an Adapter for IClientId(request), but I dont: >>> IClientId(request) Traceback (most recent call last): File "<stdin>", line 1, in ? TypeError: ('Could not adapt', <HTTPRequest, URL=http://:>, <InterfaceClass zope.app.session.interfaces.IClientId>) Shouldnt this work? Obviously I am missing something here. This is on Zope 2.10.2 with the built-in Five, and Python 2.4.4 Any help greatly appreciated! - peter.

MemoryError exception when importing a zexp file
by Ben Lobo 04 Jun '07

04 Jun '07

Hi, I'm trying to import a .zexp file that's 1.6GB but it continually fails due to a MemoryError exception. I guess that adding more RAM would probably fix this problem but does anyone know if there's any way of getting around this sort of problem without increasing the RAM? This is the traceback: -- Site Error An error was encountered while publishing this resource. exceptions.MemoryError Sorry, a site error occurred. Traceback (innermost last): a.. Module ZPublisher.Publish, line 163, in publish_module_standard b.. Module Products.PlacelessTranslationService.PatchStringIO, line 51, in new_publish c..

That, and the zope cache parameters and Database Activity plugins that I just published :) http://muninexchange.projects.linpro.no/?search&cid=14&pid=108 I am taking the liberty of CCing the zope, and munin lists on this, so perhaps others wil become aware of that usefullness as well :) And thanks for the uppdated version :) Regards Gaute Amundsen

I use ZMySQLDA quite a bit, but I have never used a blob column. According to the documentation the available types are: string, int, float and nb. I had a quick look through the ZMySQLDA source code and saw blob types being defined, but didn't see (during my quick look) how they were being used. So... try the 'nb' type and if that does not work, have a look at the source code and see how the blob types are being used. Not a whole lot of help, but maybe point you in a direction... Good Luck!

Zope 2.7 - sporadic service hangup
by Marcel Hartmann 01 Jun '07

01 Jun '07

Hi, we notice two or three times a day some kind of hangup of the zope service. After hangup there is no response requesting urls/manage interface cannot be accessed, too. Restarting the zope service resolves all problems until the next hangup. No errors in zope logs! Seems to work everything fine ... We use Zope 2.7.5-final, python 2.3.5 on Debian, to access LDAP LDAPUserFolder, ZOracleDA for Oracle Connection. I know about problems with ZOracleDA - but not resulting in hangups. What could be the reason? What can I do? Marcel
