This looks like an issue from the dim and distant past. What is the exact version you are using?
I suspect you can get this fixed by moving to a supported version or a more recent supported/community version.

Hi Andy,

Thanks for your suggestion. I am using alfresco-enterprise-4.1.4.

So it is a bug of Alfresco. How can I confirm it is failing due to Alfresco and not by our custom code.

Thanks,

Fouad

HI All,

Same error came again. Is there any way other than migrating to new version.

Thanks,

Fouad

It looks like [MNT-11098] 'Failed to get lock java.util.concurrent.locks.ReentrantReadWriteLock$ReadLock' error occurs during the star… or similar
The fix is to get the fix....

Are you adding models?
