[Zope] Importing Problem - Z2 CONFLICT Competing writes at

[Chris McDonough]

You can get more info by finding out what this object is...

cd to lib/python

invoke python

>>> import Zope
>>> app = Zope.app()
>>> app._p_jar['\000\000\000\000\000\000\023\226']
<some instance name>

What is some_instance_name?

Are you positive that there are no other threads doing any work?

Hi All,


    We are having a problem while importing a .zexp into a clean Data.fs
on Zope 2.3.0 with HotFix intalled runing on debian. We already read on
this list other messages with similar error messages. We've found a good
explanation for the message below from Chris McDonough:

"It happens when more than one thread tries to modify the same object in
storage at the same time.  It's Zope's equivalent of record-locking...
It's
normal.  There's no corruption or anything, it's telling you that it
avoided
a write that might have caused problems."

     The problem is how can we get this error if there is only one
person, one thread, making modifications to Zope?

     Despite the error below, the folder with its objects appears to be
imported normally.

     Could it be a corrupted data stored in zexp that I'm tring to
import in this new Data.fs?

     This is the error message that shows up on Zope stderr, when we try
to import the zexp:

------

Thanks in advance.
