How about the Cisco License Manager service? SSH to your publisher server and issue "utils service list" to confirm its status.

Hi mpagacz

I have checked the license manager service and it was the problem , it wouldn't start but i wasnt related to hardware issue

I found out from other community that it is a bug in my version 7.1.3 that when license exceeded certain limit that license service doesn't work

so i resolved the issue by deleting some licenses files

Also this issue was reported solved in 7.1.5 so i and doing the upgrade

anyway i have bought version 10.5 and will do the migration
