Adaptive Processing Server is restarting often - BO 4.0 SP02 Patch 6

Hello,

we are running BO 4.0 SP02 Patch 6 on Windows Server 2008 R2. The content was migrated from BO 3.1 without problems during the migration process.

Now we have the problem that the Adaptive Processing Server is restarting several times during a day. Sometimes it runs for hours, sometimes it restarts multiple times during an hour. The restart takes some minutes and during that time the server is under heavy load and no charts can be displayed in WebIntelligence.

The other server processes aren't affected and are running without reboots.

Anyone has a solution for this?

Any help is greatly appreciated!

Thanks in advance

Matthias
