Scalix 11.4.1 U1 available for download now

[florian]

All,

We've just put up Scalix 11.4.1 U1 to the download server. This is a small patch upgrade to Scalix 11.4.1, fixing two SWA issues related to resource booking and read receipts (previously provided as hotfixes to some commercial customers) and containing a 'speculative' fix for the IMAP folder cache corruption that has been seen on various versions of Scalix 11 and that has been discussed on this forum, too.

Full details - as always - can be found in the Release Notes available at http://downloads.scalix.com/.community/ ... NOTES.html

One word on the IMAP fix and it's tag as 'speculative'. While we had a number of reports from both commercial customers and community members and have even seen the issue on our internal servers, although very infrequently, we were unable to reproduce this in a lab environment. Therefore, the fix was developed based on some assumptions what may possibly be causing it - a randomly occurring race condition in the code. We have deployed a version of the code including this fix on our internal servers for a while as well as provided it to a number of support customers before this public release and the issue hasn't occurred anymore in any of these installations. The fix is certainly safe to install for all Scalix users. Please add to the respective threads should you still be seeing the cache corruption after installing this version. Also, please note that while the fix should prevent future cache corruption, it does not automatically clear already corrupted caches. Therefore, it may be necessary to do this manually once after the upgrade - again, the procedure is documented elsewhere in the forums.

Also note that there have been no updates to the Outlook Connector in this patch release, so the downloads remain at 11.4.1 (without -U1) for the Windows ZIP file.

Hope this helps and thanks for your feedback,
Florian.
