Do you have Publisher.
If yes then I would like to suggest to remove all the files in end user I.e server directry. Take proper back ups and schedule it again.
This will resolve your problem.
If not then go to Application folder there delete .meta, .pgo, and . shared files After taking proper backups and must stop server from services.
Then restart the services.
This will definately help you out.
I just did an upgrade for a Client from version 9 SR5 to 10 SR3 and all the CALS were lost.
I've reverted the the VM server back but would like to know how I can get the CALS to persist after the upgrade.
Was the problem really fixed in 10 SR2? Is there a way of backing up the CALS and restoring them after the upgrade?
ps First ever upgrade of Qlikview server...
