Hi Martin, I have tested 0.7.7 and 0.8.5 code.They both have metadate error. I find I missed some information in last email. Ip1 log in between (1) and (2) and sdi became a path of 36001405b7679bd96b094bccbf971bc90, but uevents weren't deal until (3) finished. The details described are base on code 0.7.7. I think similar process exists in 0.8.5 but there may be another to cause error. The latest "queue" code isn't tested. I will try.
