  • Import freezing at same point

    Clean import on a newly installed testing forum.
    Importing from 3.6.4 to 3.6.4
    Error happens on Threads module

    I am trying to set up a test version of a large forum I manage. My ultimate aim is to import the forum and then test merging another vBulletin forum with it. However, I cant even import the original form yet as it is constantly freeing at importing threads. It gets to 230,000 - 232,000 and it just hangs until it brings up a "The page cannot be displayed" error and the importer is not useable after. It locks up everytime I try to use it once it breaks at this stage.

    Any ideas?

    Can you just take a copy of the first database, then use that to test importing the 2nd forum into ?

      Sorry, the way we have done is is we have backed up the live database on our live server, restored it on our dev server and then trying to import this restored version. It connects fine and imports all the users, forums, usergroups, just when it hits this point in the threads does it cause issues.

      The databases are on the same server, and its a very low traffic server as its just a dev server.

        Anything in the PHP error logs ?

          No, absolutely no error logs. It just refuses to go past that stage then after Impex is completely locked up and refuses to load. I did all the suggested script changes too for large forums as this is a 4,000,000+ post forum.

            No error logs for PHP ? Eeek, thatís going to make it tricky !!

            On something that size, its probably memory or the database. PHP is going to use a huge amount of memory holding all the threadids.

            Have you turned off the PHP memory limit all together ?

              If I remember rightly our Server guy upped it to 64mb. When it first acted up it was set to 8mb but it has failed at the same point from the very first try, so I am not so sure its down to the memory limit. I have got the server guy trying another import today with this database and I have requested he search for any error reports, but each time he has checked it has come back with none. Could you confirm where these error logs would be just to make sure we are checking the correct place.

              Thanks

                Depends on the OS version and lay out, the sysadmin that built it should know exactly where the logs are, I can't think of any good reason to turn logs off, they are created for very good reasons.

                Check the php.ini to see what and where, see if this is set :

                Code:
                error_log =

                  Sorry I was getting mixed up with the db logs that you choose to enable for the Impex. I will get our server admin to look through the PHP logs.

                    Ok, we have tried another import, upped the thread limit to 5000 a time and it stalled on 225,000-230,000 (almost exactly the same point it froze at when doing 2,000 a time. Then the PHP logs were checked and there were no reported errors. So back at square one

                      True, though we have eliminated one avenue of investigation

                      Do you have any forums with a large amount of redirects ?

                      On line 107 of impex/systems/vb_36/006.php add this after the brace :

                      PHP Code:
                      echo "<br>Importing - {$thread_id}"
                      That will show you which one its working on, so which one it dies on.

                        Pretty normal amount of redirects to be honest, I will have that line of code added and run another test import.

                        Thanks for the help so far, it really is appreciated!

                          Ok we ran the import with that update to the script, it stopped at this thread:

                          http://www.ataricommunity.com/forums...d.php?t=555553

                          I dont see a lot wrong with it, I have asked our tech guy to run it once again to see if its consistantly that thread.

                            ...that take a long time (each one takes a second or so). It times out while running these selects. All in all, it seems like the SQL isn't very optimized. If we could just have it spit out the SQL we could run it from the command line and not have to worry about timeouts. I've rerun it several times and it does the exact same thing every time. I don't know enough about the importer or vBulletin to debug this.

                              And that is during the post module ?

                              That could be updating the poll id's for threads, just to check that comment out line 173 of impex/systems/vb_35/006.php.

                              Also add an index to thread.importthreadid if it isn't already there, after the 001 module, but before the thread module.
                              I wrote ImpEx.
