Hi, suddenly my kalarm went crazy and now when I add an alarm it
starts consuming CPU 100% and it doesn't stop. I have to delete the
alarm or kill kalarm. I restart kalarm and add any alarm and the
kalarm consumes 100% CPU.

If I use kalarm as another user there is no problem. So it seems that
it is a config or cache problem, but I can't find where the problem
is.

I tried several things

* Delete my /var/tmp/kdecache-<user>

* Delete all kalarm config files in ~/.kde:
share/config/akonadi_kalarm_resource_*
share/config/kalarmrc
share/apps/kalarm/*

* Delete all alarms

and the problem persists. Can you suggest me something else to try?

As a last resource I would try to delete my whole ~/.kde (or rename it
temporarily), but I should then reconfigure all my KDE.

SYSTEM: KDE 4.10.4-1 on Fedora 19, kernel 3.9.5-301, processor
i5-2450M.

TIA, Mario

couple of thing to try:

there is kalarmdrc and kalarmui.rc in share/config try renaming them

run:

Code: Select all

kbuildsycoca4 --noincremental  2> /dev/null

@google01103: Hi, I don't have those files kalarmdrc, kalarmui.rc !!

I tried to rebuild the cache with kbuildsycoca4 but it doesn't fix the problem.

Thanks for your help!

the kalarmui.rc is in apps not config so you had already deleted it
the kalarmdrc might be cruft from an older release as it's dated 2009

the kdecache-<user> should be cleaned with KDE not running

I don't quite understand you. Neither kalarmui.rc, kalarmdrc, exist. I
looked at a newly created user, and after calling `kalarm' the files
aren't there for that user neither.

Something else you could try would be to delete the KAlarm calendars from Akonadi. Run akonadiconsole (which you may have to install), and in the first tab, there should be at least three KAlarm calendars listed. Remove these and see whether that helps.

I has mentioned before, I tried already to delete the whole directory
~/.kde/share/apps/kalarm/, which includes these calendars

~/.kde/share/apps/kalarm/calendar.ics
~/.kde/share/apps/kalarm/template.ics
~/.kde/share/apps/kalarm/expired.ics
~/.kde/share/apps/kalarm/displaying.ics

It doesn't worked.

I launched akonadiconsole and in the first tab ("Agents") I see three
entries: "Active Alarms", "Archived Alarms", and "Alarm Templates". Do
you mean to delete those? (Screen capture

Well, I tried to delete the kalarm entries in "Akonadi Console" and the
problem persists. More ideas?

You say you tried to delete those entries - did you succeed? On the assumption that you did succeed, KAlarm should then have shown no alarms, and using View -> Calendars, should show no calendars either until you restart it. Did you restart KAlarm after that - does it still use 100% CPU even after restarting it?

I succeded in deleting those entries. The sequence is as follows

. I start with kalarm not running.

. Launch Akonadi Console

. Remove the 3 calendar entries

. Akonadi Console doesn't show any calendars

. Now launch kalarm

. Kalarm doesn't allow me to create entries, because I need to have a
calendar.

. Back to Akonadi Console, I create a new calendar "My Calendar"

. In Kalarm, it lets me add an entry.

. The CPU goes to 100%, laptop starts heating

. I delete the alarm

. CPU goes to normal values

Thank again!!

what type of alarm?

google01103 wrote:what type of alarm?

The simplest on: 23:00hs, text "dshdgshgds", no recurrence.

I read somewhere that alarms with recurrence can cause problems, so
the first thing I tried was to delete all recurrent alarms, but that
dind't work.

So, as a summary: I have no alarms now, and when I set one alarm (the
simplest possible) CPU goes to 100%.

Wait, it seems that now it's running OK, i.e. NOT consuming 100%
CPU. I don't know what has changed. I will mark the problem as
solved, but I don't understand what happened.

Thanks to all who helped!

Just to be sure, did you verify that it the kalarm process which was consuming 100% CPU, and not some other process?

Confirmed that it was kalarm. When the problem is present I launch
`top' and I see kalarm consuming 100% CPU.

As I told before, the problem seems fixed now. I had some trouble in
recovering the system, since I had all my calendars deleted. But it
seems that now I have kalarm fully functional.

I'm a big fan of kalarm, though I do a rather basic usage of it.
