Re: [galaxy-dev] Job execution order mixed-up
Thanks for the information. I believe I have seen a similar problem before where we get a bunch of empty histories. We also use MySQL and MyISAM and Separate web/handlers but are moving to InnoDB in mysql.

Ilya's work has been documented here: https://trello.com/c/uVYR3IHc and he kindly updated the wiki to reflect these problems. The Galaxy team already strongly recommends Postgres over MySQL - but if you have to use MySQL please use InnoDB tables (the new default) instead of MyISAM. -John On Sat, Dec 7, 2013 at 9:36 AM, John Chilton chil...@msi.umn.edumailto:chil...@msi.umn.edu wrote: Hello Yves, duplicates the history the same amount of times as the number of threadpool_workers we have configured for the job handlers Well that shouldn't be happening.

This is greatly appreciated! I didn't really made any progress in tracking down this error, and hopefully this weird behaviour will not happen anymore with the November 4th, distribution. But here are my answers to your questions, in case it would ring a bell: 1.Has this behaviour been reported with any other workflow? It has been reported with 2 different workflows as of now. These 2 workflows doesn't have anything in common, except that they are huge (one of them has 37 steps, producing a total of about 110 datasets). 2.Are you running Galaxy as a single process or multiple processes? If multiple processes, how many web, handler and manager processes do you have and are they all on the same machine? We are running Galaxy in multiple processes with 5 web servers, 3 job handlers and no manager (I believe the manager was rendered obsolete in one of the latest Galaxy distributions). All these processes are run on the same machine. 3.Have you made any modifications to Galaxy that could result in this behaviour? No. 4.What is the value of track_jobs_in_database in your universe_wsgi.ini configuration file? We never touched this part of the configuration file and the line still reads: #track_jobs_in_database = None. After reading your answer, I've decided to modify this line to: track_jobs_in_database = True Unfortunately, running one of the faulty workflows several times (5x), I noticed that one of them was still showing this strange behaviour where some jobs were executed before their inputs were ready. Do you think this issue could be related to the fact that we are using Galaxy with the multiple processes configuration? We implemented this configuration some time ago because some of our users were complaining about the slow responsiveness of the web interface. Would you recommend using Galaxy without the multiple processes configuration? (Lets say if updating to November 4th distribution doesn't fix this issue) I guess you are probably using the multiple processes configuration as well on Galaxy main? Thanks again for your help! Jean-François - Posted by *John Chilton* on *Nov 09, 2013; 2:50pm* Hello Jean-François, Have you made any progress tracking down this error? This appears very serious, but to tell you the truth I have no clue what could cause it. The distribution you are using is pretty old at this point I feel like if it was a bug the exhibited under relatively standard parameter combinations someone else would have reported it by now. Can you tell me some things: has this been reported with any other workflows? Is there anything special about this workflow? Can you rebuild the workflow and see if the error occurs again? Additional questions if the problem is not restricted to the workflow: are you running Galaxy as a single process or multiple processes? If multiple processes, how many web, handler, and manager processes do you have? Are they all on the same machine? Have you made any modifications to Galaxy that could result in this behavior? What is the value of track_jobs_in_database in your universe_wsgi.ini configuration file? -John On Thu, Nov 7, 2013 at 10:34 AM, Jean-Francois Payotte *[hidden email]* http://dev.list.galaxyproject.org/user/SendEmail.jtp?type=nodenode=4662520i=0 wrote: Dear Galaxy mailing-list, Once again I come seeking for your help.
