ZServer uncaptured python exception ...

Hi to all, I have the following error causing shutdown of the zope server. the system is SunOS SERVER 5.8 Generic_108528-12 sun4u sparc SUNW,Ultra-2. With ZOpe installed from Zope-2.5.0-solaris-2.6-sparc.tar file . To debug the problem, for a period, i started the server with this parameters: /usr/local/zope/start -u nobody -w 81 -M /usr/local/zope/DETAILED_LOG.txt STUPID_LOG_FILE="/usr/local/zope/STUPID_LOG.txt" & And for all this time the server has never died. Yesterday, believing it was a temporarly failure, i set the strat at the default: /usr/local/zope/start -u nobody -w 81 & But after i made this the server restart to die. SOme one have ideas? Thank you in advice. This is a quote of the STUPID_LOG_FILE. 2002-05-23T13:42:11 ERROR(200) ZServer uncaptured python exception, closing channel <ZServer.HTTPServer.zhttp_channel connected 217.72.34.172:10806 at 0xbd9eec channel#: 2607 req uests:> (socket.error:(11, 'Resource temporarily unavailable') [/usr/local/zope/ZServer/medusa/asynchat.py|handle_read|82] [/usr/local/zope/ZServer/medusa/http_server.py|recv|420 ] [/usr/local/zope/ZServer/medusa/asyncore.py|recv|357]) ------ 2002-05-23T13:42:34 ERROR(200) ZServer uncaptured python exception, closing channel <ZServer.HTTPServer.zhttp_channel connected 217.72.34.172:10810 at 0xc03544 channel#: 2611 req uests:> (socket.error:(11, 'Resource temporarily unavailable') [/usr/local/zope/ZServer/medusa/asynchat.py|handle_read|82] [/usr/local/zope/ZServer/medusa/http_server.py|recv|420 ] [/usr/local/zope/ZServer/medusa/asyncore.py|recv|357]) ------ 2002-05-23T13:47:52 ERROR(200) ZServer uncaptured python exception, closing channel <ZServer.HTTPServer.zhttp_channel connected 217.72.34.172:10843 at 0xaa226c channel#: 2632 req uests:> (socket.error:(11, 'Resource temporarily unavailable') [/usr/local/zope/ZServer/medusa/asynchat.py|handle_read|82] [/usr/local/zope/ZServer/medusa/http_server.py|recv|420 ] [/usr/local/zope/ZServer/medusa/asyncore.py|recv|357]) ------ 2002-05-23T14:12:07 ERROR(200) ZServer uncaptured python exception, closing channel <ZServer.HTTPServer.zhttp_channel connected 217.72.34.172:11094 at 0xbdafe4 channel#: 2737 req uests:> (socket.error:(11, 'Resource temporarily unavailable') [/usr/local/zope/ZServer/medusa/asynchat.py|handle_read|82] [/usr/local/zope/ZServer/medusa/http_server.py|recv|420 ] [/usr/local/zope/ZServer/medusa/asyncore.py|recv|357]) ------ 2002-05-23T14:17:42 ERROR(200) ZServer uncaptured python exception, closing channel <ZServer.HTTPServer.zhttp_channel connected 217.72.34.172:11168 at 0xa2188c channel#: 2751 req uests:> (socket.error:(11, 'Resource temporarily unavailable') [/usr/local/zope/ZServer/medusa/asynchat.py|handle_read|82] [/usr/local/zope/ZServer/medusa/http_server.py|recv|420 ] [/usr/local/zope/ZServer/medusa/asyncore.py|recv|357])

Library for huge text indexes ..
by Jean Jordaan 29 May '02

29 May '02

Just spotted this and wondered if it might be of interest to people working on Zope's indexing capacity .. http://www.gnu.org/software/mifluz/description.en.html The purpose of GNU mifluz is to provide a C++ library to build and query a full text inverted index. It is dynamically updatable, scalable (up to 1Tb indexes), uses a controlled amount of memory, shares index files and memory cache among processes or threads and compresses index files to 50% of the raw data. The structure of the index is configurable at runtime and allows inclusion of relevance ranking information. The query functions do not require to load all the occurences of a searched term. They consume very few resources and many searches can be run in parallel. -- Jean Jordaan Upfront Systems http://www.upfrontsystems.co.za

Replacing default Python with ActiveState 2.1.3
by hpinson＠indepthl.com 29 May '02

29 May '02

Hello. I am trying to replace the standard zope Python with the ActiveState version (2.1.3) so that I may enable Perl scripting. Can anyone tell me what paths, in what files, have to be changed in the Zope configuration to point to the new Python? My zope is at d:\zope My Python is at c:\program files\python If there is a howto on this that anyone knows about-- this would be useful too? Thanks.

RE: [Zope] Zope alone or under Apache
by Meilicke, Scott 29 May '02

29 May '02

My experience with a low volume personal site on linux (debian), versions 2.3.x through 2.4.3, is that zserver crashed every few days. When I put Apache in front with mod_proxy, it no longer crashes. This site is exposed to the Internet. At work I use zope 2.4.3 on windows, no apache or IIS, and I have never seen it crash, but it is not exposed to the Internet either. Scott -----Original Message----- From: Fearless Froggie [mailto:fearless_froggie@yahoo.com] Sent: Tuesday, May 21, 2002 10:13 AM To: zope(a)zope.org Subject: [Zope] Zope alone or under Apache >From my research I understand that Zope alone is much faster than under Apache. Are there any advantages to running Zope under Apache that would make the decrease in speed worthwhile? There seem to be plenty of zope products available to take care of things missing in zope like cgi-bin, etc. I'd be grateful for any "personal experiences" people would have to offer.

Zope's version of python
by Patrick Hresko 29 May '02

29 May '02

Hello, I am looking to do XSLT transformations with Apache's Xalan engine. I am also using Pyana to interface python with Xalan. I am under the impression that Zope uses its own version of Python (2.1.2). I was wandering how I would go about installing modules so that Zope's version of python would recognize them. Thanks, Patrick Hresko

Apache 1.3.22 / 1.3.23 on RedHat 7.2/7.3
by Adam Manock 29 May '02

29 May '02

I'm currently evaluating RedHat 7.3 for use on our servers. We're currently standardized on RH7.2 with few problems, unless you count maintaining a 1.2Gb mirror of updates.redhat.com/7.2/en/os/ errata packages a problem :-) A little advance digging for potential sticking points revealed the mod_proxy cookie bug: http://nagoya.apache.org/bugzilla/show_bug.cgi?id=7195 So, has anyone tried using RedHat's apache-1.3.22-2 packages from RH7.2 errata on RH7.3?
