There it is again this bug. We have to find a way to reproduce it! Meng, can you reproduce this bug with a small dataset? Try loading only 50 tuples or so and re-run this query to see if clientport disappears again. If so, please send us the small dataset so we can reproduce it. thank you! lefteris On Thu, Aug 8, 2013 at 10:21 AM, integrity <357416268@qq.com> wrote:

Dear Meng, Could you please keep this mail channel free from very application specific issues!!! It reaches many that don't have a clue about your application setting, nor the time to help you in this. For them this turns into spam. I urge you to scout locally for a database expert to help you debug your software. In case of a potential bug, we are more then welcome to study the minimal, fully documented and repeatable setup. Furthermore, the mail list archive is a good source for additional information about phenomenons observed. regards, Martin On 08/08/2013 09:21 AM, integrity wrote:

Hi Martin,
The last mail i sent just is a show of some bug in MonetDB,
It demonstrated a realistic application of MonetDB in Internet Industry, which is the first time MonetDB applied in the Top 3 internet company ,a valuable example MonetDB applied to.
I just want to help improve MonetDB by fixing some little and serious bug , this is out of my passion for it.
Regards,
Meng

"In case of a potential bug, we are more then welcome to study the minimal, fully documented and repeatable setup." Non of this is provided and no bug report is filed. If it can not be repeated independently then it is not a "bug" we care about.
I just want to help improve MonetDB by fixing some little and serious bug , this is out of my passion for it. That is well recognized by the effort put forward by the core team helping you, but it is not our job to hold hands in application development.
