Kontact has been working fine for a long time, but some days ago it freezes after starting up.

I can click a little during the start and it might show a mail or two, but after that, it is locked. I can still move the mouse around, I can resize the window, minimize and restore, but no functions inside the window/program.

If I start Kmail or Kaddressbook on as standalone apps, they work fine.

Now and then I have had some mysql errors that usually has gone away after a restart. But now, when using Akonadi tray and check a little, they mysql log has these errors:

Code: Select all

Still, according to Akonadi tray, Akonadi is running.

Any idea? I have checked others with similar problems and can not find anything about this in any faq. But maybe I am not using the correct search terms, so I am happy to get some specific links

It sounds as though something has corrupted your database. Take a look at http://userbase.kde.org/Akonadi_4.4/Tro ... .27t_exist - that looks very similar, so it's worth a try.

Great! That took care of one part of the problem.

I do not have the same innodb problems, so I left out the second part of it. I am left with this in the mysql error log now:

These are the ones I am trying to solve first:

A FEDERATED plugin
Time zone tables do not exist
Privilege tables - mysql.servers - do not exist

Plus the rest

EDIT: Almost forgot to mention - I am running Kubuntu 9.10 with KDE 4.4.1

Do you have selinux? Or apparmor? If you do, you probably need to add an exception.

Could very well be. I have no idea if I do, I am running whatever is standard in Kubuntu 9.10. So I will look and see if I can find a KDE app that takes care of that bit.

Ok. I am probably using apparmor and there are two files I guess can influence Akonadi and mysql:

usr.sbin.mysqld
usr.sbin.mysqld-akonadi

There are three errors that relates to files that can not be opened. And one related to a missing table. I guess the missing table can not be fixed by anything done through apparmor. Does anyone have any idea how this table can get fixed?

I am trying to search through my computer to find out if the files mention here are present. Where should they be?

100327 11:34:47 [ERROR] Cannot open mysql.db
100327 11:34:47 [ERROR] Cannot open mysql.user
100327 11:34:47 [ERROR] Cannot open mysql.event

Try http://userbase.kde.org/Akonadi_4.4/Tro ... g#Apparmor - there seems to be a fix there.

Yeah, tried those. No change. Absolutely nothing at all. And to make sure that anyone reading this get the full picture, here is the full testreport from Akonadi:

The error encountered with MySQL only affects MySQL's ability to perform certain operations, and does not affect usage of its database queries and as such is inconsequential to Akonadi.

It is solvable through running mysql_install_db with Akonadi stopped. Note that you may need to disable AppArmor or SELinux for it to function correctly.

I tried running it in a terminal and got

mysql_install_db: command not found

As I am not familiar with the command, could you please advice how to run it or where to find it? I have been trying to search on Google, but basically just finding the same as you said here. So it seems everyone is assuming something I do not know about...

I don't know kubuntu, so someone else will have to advise on that. Meanwhile, have you already tried the tip in http://userbase.kde.org/Akonadi_4.4/Tro ... .27t_exist ?

It was the first link you pointed to and I read everything then. And responded accordingly Thx. for helping!

It's clear that you have a mysql problem. Try speaking to the kubuntu channel on IRC or asking their mailing list.

Well, seems that 4.4.4 is my lucky number!

I upgraded today and restarted. Then fired up Kontact just to check, although I must admit my hopes were not too high. So the surprise and joy was even bigger when it turned out that it actually was back to working condition again!

One thing that managed to hang it was the RSS reader. After clicking on that one, Kontact stopped responding. There is of course the chance that this has been a problem the whole time and something in Kontact allowed this to effect the whole app...

Anyway - I went to the config and deactivated the RSS reader as for now it is not working for my purpose. Akregator is a good reader, but it is totally unable to handle the number of feeds I need, so for now, RSSOwl is the best reader for me.

I will test Kontact over the next few days and report back if I get any problems.
