Well, I think this has been fixed, but it's not so benign ;-)
By catching a ConflictError like this, I'm pretty sure you can end up 
with inconsistent index state saved in your ZODB :-(

You may consider my "ManagableIndex" and its "KeywordIndex".
It has less bugs than the Zope one -- and should you find one,
the fix will almost surely be much quicker than for Zope indexes ;-)

Re: [Zope] error (200)

[Mike Mikkelsen]

Turns out ZopePTK already has it's own LoginManager.  When I installed the
LoginManager product, ZopePTK died.  From there other products started acting
weird and zope became unstable.

I couldn't fix it with tranalyzer.py and split.  So I exported all folders off
the root, rm -rf'd the zope dir and started over.

Everything is ok now.

Thanks for all the replies.

I got this error after updating LoginManager, but, not the PTKDemo which
caused these errors.

Have you tried upating PTKDemo via CVS (if you're using PTK)? After I updated
these errors went away, or updating any Products you have that use the 
LoginManager?

It could be related to an old LoginManager instance hanging around.
Try removing and re-adding LoginManager instances.

The error means that Zope could not unpickle the object with
the given object id.

I, once, had this problem. I had changed (deleted?) a class
in one of my products. An object in the ZODB referenced this
class, unpickling failed. The problem disappeared
after restoring the old state.
I, now, delete objects in Zope before I delete classes in
a project that is required by the objects.

Re: [Zope] error (200)

[Martijn Pieters]

So, Tranalyzer says nothing is wrong, but you do get a load state error. 

Next thing you could try is truncate the Data.fs to the point where things
started going wrong. Tranalyzer will tell you for example at which point your
Products were installed. If I read things right, the value after the @ of that
record is the byte offset of that record in Data.fs. 

You can now use split to truncate Data.fs to that point. Make sure you then
test Data.fs on a Zope install _without_ the offending Products!

You can use this technique to further and further back in time to the point
that things are still sane.

Have a look at Ty Sarna's Tranalyzer:

  http://www.zope.org/Members/tsarna/Tranalyzer

which can tell you where your Data.fs is in trouble. You then can try and
repair your Data.fs file by truncating the file at the point of corruption.

[Zope] error (200)

[Mike Mikkelsen]

Hello all,

My Zope (2.1.6) installation has just become *very* unstable.  My most recent
addition has been ZPatterns and LoginManager.  My passwords for my virtual
sites (using SiteRoot) are no longer accessable by my account and superuser
can't access them.  The site "disappears" three or four times a day without
errors.  And clicking on Product Management link sometimes returns "No Data"
notice in the browser and then Zope crashes.

This is the error that shows up on the console when going to Product Management
or accessing the subdir that holds the subdir that has LoginManager:

 ERROR (200) ZODB Couldn't Load State for
'\000\000\000\000\000\000\002\017'


I'm exporting the sites now and am going to (I guess) re-install zope and all
of the products. >8-/

Are there any other options?
Any ideas on what went wrong?
Is their a way to fix a corruption in the ZODB?


TIA
