 Description   

We have our public instance setup to use a shared repository and have a customer requirement to have RSS Aggregator run and import updates every few mins. When we run the public instances with clustering (on same db), we run into an issue where each of the instances is throwing a javax.jcr.InvalidItemStateException:

info.magnolia.module.data.importer.ImportException: Error while importing with handler [rssaggregator]:can't create parent [/rssaggregator]:202013d7-cf55-41ec-8cab-5a8e1c923d67/{}importState: the item cannot be removed because it has been modified externally.

This is causing the RSS Feeds to not display at all on public instances.

Note that running a clustered environment is essential to achieve the required level of scalability so only running aggregator on one of them is not acceptable.

Because we are finishing 4.4.6 release this issue should be part of 4.4.7 release or Scheduler module will be released independently.

Is there any update on this yet please?

Hi Rory,

since this ticket is duplicate of MGNLSCH-15 I'm closing it. You can watch progress on MGNLSCH-15, it should be implemented during next week. Once this is done I'll update the ticket so you can use SNAPSHOT version of Scheduler module until the final release is available.
