Additional code changes were made to prevent SQL deadlocks from occurring.
Symantec has developed a new Axengine.exe to resolve this issue. It is attached to this KB.
To apply the fix do the following:
1) Stop all Deployment Server services - (Altiris Express Server, Data Manager, DB Management, PXE)
2) Rename current axengine.exe in Deployment Server share to axengine.old
3) Copy axengine.exe from this KB into the Deployment Server share.
4) Restart all DS services and restart DS console.
