I currently am running 4 Ambas. 1 of the 4 Ambas will not display all of the thumbnails in zookeeper. The other 3 machines will show all thumbnails for all machines, including the one that isn't showing. The bad machine will not show all the thumbnails for the other machines as well.
Here is what I have tried:
1) f12 (ambas version of f11) the machine 2) Upgraded (by uninstalling first) to V 4.1.023010 3) Sync content from another machine to bad machine 4) Deleted content in media manager on bad machine and sync content. 5) Deleted the V4 media folder, then reinstalled, and re-sync all content.
Everything I've tried resulted in exact same results. Like I said before this is only a problem on one machine while on that machine.
This issue has been dealt with. Media folders had been moved around and MediaManager got confused and couldn't "read" the thumbnails. A new media folder was created, media was brought in properly and thumbnails work fine.
