Description:
In what scenario will the, "com.tibco.as.space.ASException: INVALID_OBJECT (metaspace_invalid)" exception be throw?
Symptoms:
com.tibco.as.space.ASException: INVALID_OBJECT (metaspace_invalid) exception is thrown as-agent/ as-admin log file / console.

Cause:
The com.tibco.as.space.ASException: INVALID_OBJECT error occur when an underlying metaspace needs to migrate to a different metaspace. This usually happens when there is a network failure/memory related issue. Network related issues causes a condition where there could be multiple clusters running independently. Once the network is restored, they will discover each other and the cluster with a smaller member will migrate to a bigger cluster. This migration causes space references to become invalid, throwing INVALID_OBJECT exceptions. BW does not expose the space reference to the user, so it is not possible to fix this without restarting the BW engine.
