Why the transactions not started are null, no sql statements can be seen ? ---TRANSACTION B8F1250D, not started
MySQL thread id 2874150, OS thread handle 0x10ff, query id 2487509285 192.168.1.111 webadcc
---TRANSACTION B8F094C9, not started
MySQL thread id 2874100, OS thread handle 0x10dd, query id 2487481983 192.168.1.69 webapp33
---TRANSACTION B8EE7088, not started
MySQL thread id 2873921, OS thread handle 0x10f2, query id 2487377720 192.168.1.111 webadcc
---TRANSACTION 0, not started

do I need to do some more optimization ?
