Hello, I receive the error in many different ways. One way I was able to reproduce it,
3 different users (unique logins) try to confirm production of a bill of materials. Granted it was the same one, 2 users received the error while the third succeeded. Another way I receive the error frequently is installing new modules, I have been able to reproduce the problem on 10 systems with current code easily, but other openerp core developers say they cant reproduce it. The problem seems worse when trying to install module from the kanban view. The issue besides the error message is not being able to run the configuration wizards. Another way I was able to reproduce it is by trying to import orders using magento connection. I see the error a lot in this way. Olivier you explain a possible relief, I will see about having this developed in a module or something -- You received this bug notification because you are a member of OpenERP Indian Team, which is subscribed to OpenERP Server. https://bugs.launchpad.net/bugs/992525 Title: TransactionRollbackError due to concurrent update could be better handled Status in OpenERP Server: Confirmed Bug description: While using openerp, psycopg2 raises TransactionRollbackError quite often even on small database. This does not seem to be easily reproduceable as it seems to be a conflict between two thread accessing the same table. Nevertheless, I provided a quick video reproducing this while installing "base_crypt" on my computer. This occurs mostly at module installation. And can completely mess up the module installation by giving empty wizard windows of instance. I guess it could also occurs in other situations (in multi-user context), where the bug would be quite difficult to reproduce and with unforeseeable consequences ;) I've spotted an other bug that is due to this it seems: https://bugs.launchpad.net/bugs/956715 In my case (single user), it seem to hit more often on fast computers. To make a probable better guess, it seems to hurt more often whenever using a local connection between the browser and the server. It could be about the web module trying to update the res_users session info and may collide with normal operation. On my computer, from a new database, installing the 'base_crypt' will trigger the exception. When using a distant connection, the bug won't show up. Please check the video I've posted with the bug report if you want to have more detail on the procedure I used. Sorry for the bad sound recording. Note that the video will show you the bug occuring on my computer and NOT occuring on a distant computer. I'm providing a merge proposal along with this patch which solves the issue for me, but need a patient review.
