Sintomi

A restore operation from AppSync GUI will eventually hang and fail due to a timeout error.

The AppSync events will show:

In server logs will see it's timing out:

Causa

A number of snapshot were involved in the restore operation which caused delay/timeout. Possible cause not determined however this could be a performance/slowness issue on resources like array and host.

Risoluzione

Adjusting the transaction timeout value will allow AppSync not to timeout during restore operation.
  
  1. Go to C:\EMC\AppSync\jboss\standalone\configuration\standalone.xml.
  2. Change the value from default of 300 to new value 2400 seconds - <coordinator-environment default-timeout=2400
  3. Stop all the Services (EMC AppSync Datastore and EMC AppSync Security service)
  4. Start the services(EMC AppSync Datastore Service, EMC AppSync Security Service, EMC AppSync server service)
