 limi    getting ConflictERrors in collector, ZWiki   
 run|osx both are using dictionaries   
 run|osx so you can easily get conflicterrors when you are chaning stuff  and people are reading it at the same time    
 run|osx thats why we should move to PCNG and get ZWiki to use BTree's

I see increased conflict errors in the zwiki.org logs (though not in the UI) in the last version or two. See also #665 performance regression on zwiki.org.

NB Zwiki will work with a BTreeFolder?.. it would be interesting to see if it affects this problem.

new code to try --SimonMichael, Tue, 13 Jan 2004 07:07:52 -0800 reply
Also, it would be interesting to see if the latest zwiki-cvs code (with new page hierarchy code) helps.

apparently rare, lately --SimonMichael, Sat, 24 Jan 2004 19:09:19 -0800 reply
