CAUSE:
Bug# OE00188661
CAUSE:
When writing notes into BI clusters, if the free space left in a cluster is between 76 and 80, and at the same time, an AI extent switch note (caused by aimage new command) is going to be written into that cluster, aimage new may fall into a dead lock with itself.
FIX:
Upgrade to 10.2A02 or later.
