ConflictError from Products.Transience.TransientObject.TransientObject
by Chris Withers 04 Aug '10

04 Aug '10

Hi All, I have an old Zope 2.9.8 instance which has recently started throwing the following unresolved ConflictErrors: Traceback (innermost last): Module Zope2.App.startup, line 173, in zpublisher_exception_hook Module ZPublisher.Publish, line 121, in publish Module Zope2.App.startup, line 240, in commit Module transaction._manager, line 96, in commit Module transaction._transaction, line 380, in commit Module transaction._transaction, line 378, in commit Module transaction._transaction, line 433, in _commitResources Module ZODB.Connection, line 479, in commit Module ZODB.Connection, line 1050, in _commit_savepoint Module tempstorage.TemporaryStorage, line 202, in store ConflictError: database conflict error (oid 0x046a, class Products.Transience.TransientObject.TransientObject, serial this txn started with 0x0387c9f23edea155 2010-07-27 10:26:14.735074, serial currently committed 0x0387c9f28a1ff766 2010-07-27 10:26:32.373016) To my knowledge, the request that throws this isn't touching the session or temp_folder, but I guess something is. How can I find out what code is actually touch this and so causing this conflict? Chris -- Simplistix - Content Management, Batch Processing & Python Consulting - http://www.simplistix.co.uk

zope timeouts
by Michele Marcionelli 28 Jul '10

28 Jul '10

Hello I'm running an old version of Zope which is required by our corporate design using also an older version of the CMS Silva: Linux Distribution: Red Hat Enterprise Linux Server release 5.5 Linux Kernel: 2.6.18-194.8.1.el5PAE Zope: 2.8.9.1 Python: 2.3.6 (with several modules, like: ldap, pil, mysql, pyxml, ...) Silva: 1.5.13 My problem ist that my zope server hat timeouts on displaying pages after a while that it has been started (currently this "while" is approx. 15 minutes). The only thing that helps is restarting zope. By accident I discovered about two month ago, that running an "strace -f" on the zope process, "reactivated" it... so I could live with this hack until yesterday. Now I'm running "strace" permanently (with all the disadvantages) and zope works "fine" for about 1 to 1.5 hours. Here is a short recurring output of "strace": > [pid 13408] <... futex resumed> ) = 0 > [pid 13406] futex(0xbcc12c0, FUTEX_WAIT_PRIVATE, 0, NULL <unfinished ...> > [pid 13405] futex(0xbcc12c0, FUTEX_WAKE_PRIVATE, 1 <unfinished ...> > [pid 13408] futex(0xbcc12c0, FUTEX_WAKE_PRIVATE, 1 <unfinished ...> > [pid 13407] <... futex resumed> ) = 0 > [pid 13405] <... futex resumed> ) = 1 > [pid 13408] <... futex resumed> ) = 1 > [pid 13405] futex(0xbcc12c0, FUTEX_WAIT_PRIVATE, 0, NULL <unfinished ...> > [pid 13408] futex(0xbcc12c0, FUTEX_WAIT_PRIVATE, 0, NULL <unfinished ...> > [pid 13406] <... futex resumed> ) = 0 > [pid 13406] futex(0xbcc12c0, FUTEX_WAIT_PRIVATE, 0, NULL <unfinished ...> > [pid 13407] futex(0xbcc12c0, FUTEX_WAKE_PRIVATE, 1) = 1 > [pid 13405] <... futex resumed> ) = 0 > [pid 13407] futex(0xbcc12c0, FUTEX_WAKE_PRIVATE, 1 <unfinished ...> > [pid 13405] futex(0xbcc12c0, FUTEX_WAIT_PRIVATE, 0, NULL <unfinished ...> > [pid 13408] <... futex resumed> ) = 0 > [pid 13407] <... futex resumed> ) = 1 > [pid 13407] futex(0xbcc12c0, FUTEX_WAIT_PRIVATE, 0, NULL <unfinished ...> > [pid 13405] <... futex resumed> ) = -1 EAGAIN (Resource temporarily unavailable) I need definitively help...

Plone Conference Earlybird rate ends in 9 days
by Matt Hamilton 22 Jul '10

22 Jul '10

Hi All, Just to give any of those who are thinking of going a poke, the 8th International Plone Conference is happening here in Bristol, UK at the end of October. The bargain earlybird rate of £250+VAT for the 3-day conference ends at the end of the month.... just 9 days time! So go register your tickets now: http://www.ploneconf2010.org/ We are expecting over 400 delegates from around 30 countries to be attending, with over 50 talks, plus training, sprints, and an un-conference day. We will be putting a call out for speakers and training sessions shortly. As a slight aside... if you want to see how quick it is to get Plone 4 up and running, here is a screencast I just did at Europython yesterday in which I go from nothing but python installed to fully installed and running Plone instance in under 3 minutes: http://is.gd/dAqs1 -Matt - Matt Hamilton matth(a)netsight.co.uk Netsight Internet Solutions, Ltd.

They're not hiring for working alone, but in a team. BTW, Pula is a great natural place in Sardinia, worth the work :D P.S. best of luck to Marco, from which I've learned Zope, Python and ... IDE integration :-)
