During or immediately after a deployment, the site may perform poorly due to one of a few similar Java deadlocks or see transaction-related errors. The deployment may or may not involve Selective Cache Invalidation (SCI).
If you see similar deadlocks involving ReentrantLock on 10.2.0.3, see Deadlock Involving ReetrantLock After Upgrading to Oracle Commerce (ATG) 10.2.0.3 (Doc ID 1926976.1).
Key to all symptoms of this issue is the involvement of GSAItem.getWrappedItem() in threads that are stuck or stack traces for a transaction-related error.
In all the deadlock examples below, the red text indicates the lock conflicts involved in the deadlock, and the orange text indicates the key code showing the incorrect behavior that led to the deadlock.
