[Zope-dev] Conflict Errors; how to track them down?
Hi all, Except for SARS, another problem that's been plagueing us for months are seemingly random Conflict Errors. We see about 10 every day on our Zope 2.6.1, and they can happen on any page. In most cases they are not related to pages that actually updated anything (AFAIK), although we do use SESSIONS (but no frames). Any clue how to track down which objects are having problems, what's causing this? -- 2003-06-03T09:08:10 INFO(0) ZODB conflict error at /VirtualHostBase/http/www.beijingsammies.com:80/sammies/VirtualHostRoot/ (7 conflicts since startup at 2003-06-02T13:15:05) -- I volounteer to write up a HOWTO document regarding this and the Bad reference to errors we're also getting (see previous post) if I can just find out what's wrong.

[Zope-dev] Bad reference to ... how to find object references?
Hi all, During packing, we're seing errors such as the ones attached below. Can someone give a description how to track down which objects have these broken references? Such help would be much appreciated... -- 2003-06-03T00:55:26 ERROR(200) ZODB FS FS21 ERROR: Bad reference to ('\x00\x00\x00\x00 \x00\x0b\x9e\xb7', '') -- 2003-06-03T00:55:27 ERROR(200) ZODB FS FS21 ERROR: Bad reference to ('\x00\x00\x00\x00 \x00\x0b\x9e\xb8', '') -- 2003-06-03T00:55:27 ERROR(200) ZODB FS FS21 ERROR: Bad reference to ('\x00\x00\x00\x00 \x00\x0b\x9fy', '') -- Bye, -- Bjorn Stabell ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

If the conflicts don't correspond with entries in the undo log, and you're not mounting other databases, the conflicts are almost certainly due to sessions. However, conflicts are a normal occurrence and rarely reach the user. Zope automatically retries the request and delivers the successful page.

However, conflicts are a normal occurrence and rarely reach the user. Zope automatically retries the request and delivers the successful page. They do not always correspond to entries in the undo log. But the ones that do are always (?) committed successfully. The problem is, as I can see from other threads here, that they are related to other systems that cannot be rolled back (e.g., sending email / faxes), so we get duplicate emails / faxes. I'll look at how to wrap these systems in transaction-aware wrappers, as was mentioned in a related thread. In any case, is there no way to find out more detailed information about why a conflict happened? There must be some oids somewhere?
