Syndicators and subscribers should always be at the same build and patch level!
Here's a bit of feedback about syndication issues in Portal 6.0 - what problems (and any solutions) are people experiencing? To date I've encountered the following issues:
1. Syndication on 6.0.0.0 results in all content being "locked" on the subscriber by wpsadmin, and unable to be unlocked - permanently read-only
2. Syndication on 6.0.0.1 is unable to copy 90% of content or other items where there are permissions granted to [all users]
3. Syndication on 6.0.0.1 results in locked items in subscriber library that need to be unlocked by wpsadmin
All of these issues have occurred when syndicating from Windows to AIX installations.
Few issues I have came across, these are all problems in 6001 (fixes are available for these):
Problem:
Syndications always copies all the versions right now from Syndicator to Subscriber, this can cause large intial data copy even if versions are not required on Subscriber machine.
Problem:
Syndication is trying to send an older version of an item, but there's already a newer version of the item in its place on the Subscriber. The item existed at some point on the Syndicator, but it was deleted and another item with the same name was created in the same library. The problem occurs when WCM syndicates the old version of the item (the one that is deleted), and WCM attempts to add the item to the repository. Since an item already exists with this name, a DuplicatePathException is thrown. Any subsequent updates that reference the item also fail, and an ItemNotFoundException is thrown. Below is an example of the stack trace for an ItemNotFoundException.

Problem:
After purging an item on the subscriber and a full update is kicked off from the syndicator, the subscriber throws an exception when attempting to recreate the item because the version entry for the item still exists in the event log's version table (JCR.EV_VERSION).
