  • Users getting 65535 unread PMs

    I've been having a weird problem lately, every so often one of my users reports that their unread PM total has suddenly wrapped around. It seems to happen to someone every couple of days on a board with 100-150 simultaneous logins.

    Checking the database right now I've got guys with 65533, 65534, 65534, and 65535 unread PMs. I'm going to manually set them to 0.

    I recently changed to a new VPS a couple of weeks ago, so I've changed versions of so many different software packages that I couldn't tell you if any upgrade led to this.

    I'm running:

    VBulletin 3.5.2

    Apache 2.2.0 (Preform MPM)

    PHP 5.1.1

    MySQL 5.0.16

    The only other problem I get is that, due probably to my lowish MySQL wait timeout, every couple of days I get a VBulletin DB error that someone couldn't update their session status. The error always looks basically like this, and it seems to be it shouldn't cause the PM problem since it doesn't happen in PM-sending code and doesn't happen to the users with PM problems. I'm just posting it on the off chance you guys think it could be related, I really don't care about DB timeouts.

    Database error in vBulletin 3.5.2:

    Invalid SQL:

    (sessionhash, userid, host, idhash, lastactivity, location, styleid, languageid, loggedin, inforum, inthread, incalendar, badlocation, useragent, bypass)

    1. First, you have a db problem. I don't know what happened to it but there's definitely an issue there. You can try running Repair/Optimize in the Admin CP. You may need to run it more than once to fix all errors:

    Admin CP -> Import & Maintenance -> Repair/Optimize Tables -> Check All -> Continue

    I don't know if this will help but that's the place to start. You may have to restore a backup of the database from prior to when these problems started.

    2. Here are the reasons for the MySQL server going away error:

      I've manually run an extended check of all tables from the mysql command line. The "word" table was corrupted (interestingly, VBulletin's check reported it as OK), but everything else was fine.

      I'm not sure what kind of database corruption you're referring to if MySQL can't find anything wrong. Do you mean there may be inconsistency in the VBulletin database caused by some sort of past error in VBulletin?

      As for the suggestion of restoring the database from before the problem occurred, the "last known good" backup in that sense is from before a server move last month. I'd lose something like 20,000 posts from going back to it... and still be screwed if it turns out a problem arose in switching from MySQL 4.0.16, which I had on the old server, to 5.1 which I'm now using on the new server.

      I can't do anything that drastic just because an unread PM total wraps around once or twice a week. Do you have any other tips for looking into what might be wrong with the database?

        Be sure to include the login info to your Admin CP, phpMyAdmin and FTP. Please also include a complete description of the problem.

          We have the same issue after we upgraded our MYSQL 4 to MYSQL 5.Some of the users keep getting 65535 unread PM messages,even after we manually reset that field to 0.Is there any fix for this?


          • #6
            I'm having the exact same issue. Some members are being told they have 65535 unread private messages.

            I'm running vBulletin v3.5.4 on MYSQL 5
            I've added the ImpEx thing, so that I could switch to vB from phpbb v2.0.19
            I have no other hacks installed on the board at all.

            I too would be interested in hearing what came of this problem.


            • #7
              I've had three people report the same issue to me with my vb 3.5.3.

              I just assumed it was a left over quirk from importing PM's from my old board.
              I told my members to delete a couple PM's to fix it. However, reading this looks like it could be an on-going problem.

              My server uses mysql 5.0.19-Debian_2 with php 4.4.2 and my database originally imported from a phpbb 2.0.15 board.

                Is everyone purposely not reading post #4?

                  Is there any solution for this issue as I have it as well occasionally, do I need to open a ticket to get a fix?

                    I guess that answers my question.

                      Well I figured it may have been fixed by now and a known bug ... hence I asked .. I have logged a support ticket And I did read post #4 ..

                        No, it's not a known bug otherwise I would have posted that earlier today instead of what I did post.

                          K point taken

                          Was the original issue fixed for the thread creator ?? Or am I the only one to have actually logged a ticket?

                            I answer about 50 support tickets a day myself. This doesn't include the ones answrered by all the other support staff. So unfortumately I do not have total recall and can't tell you if he ever started a support ticket or what happened to it.

                              Just checking into say I'm having the same problem. Recently upgraded from mysql 4 to 5 and vb 3.5.2 -> 3.5.4

                              off to open a ticket now.
