Bug Description

I just upgraded from 7.04 to 7.10. My problem: 7.10 is nearly not accessible and very slow responding. My typical boot now is like that:

00:00 Start PC
00:53 Login Screen
02:10 Desktop Background image appears (the normal dark brown one)
03:00 All desktop icons are there
(I start System Monitor, which opens slow, showing scim-launcher using 300+Mb RAM - I just watch it)
(I move the mouse from time to time to prevent the screensaver coming up)
23:15 memory used by scim-launcher gets freed, all look normal)

This very high memory use can happen with other modules too. I had it also with gnome-appearance-properties and gnome-terminal. But most often it's with scim-launcher. Right now there are also 2 "scim-launcher" modules visible in "System Monitor", one running (with now 375Mb RAM in use), one sleeping). When I "kill process" it usually comes back a moment later.

Seems that this gets better after a few hours, however, that PC is not really used much right now.

Another note for the 2 scim-launcher: they have following popup comments:

running one: usr/usr/scim-1.0/scim-launcher -d -c simple -e all -f socket --no-stay
sleeping one: usr/usr/scim-1.0/scim-launcher -d -c simple -e all -f x11

right now "update-notifier" eats up all RAM.

Let me know if you need any supporting information. If you need logfiles then let me know how to find or get them as I am not a linux expert.

Once my system was suddenly down because of power fail.
When I restarted my computer,
everything is all-right but scim
either scim-bridge or scim-helper eats up all my RAM

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with latest Ubuntu release? Thanks in advance.

This bug happened to me once or twice (I am not sure if they were the same bug).

The first time, I was using Ubuntu Intrepid + Xubuntu Desktop. It once crashed for no obvious reasons. After rebooting, Xfce ran emtremely slow. It took about 20 minute to display the desktop, with blanks here and there, totally unusable. I simply formatted the whole partition then, as I didn't want to bother with unknown bugs.

The second time, just now, I was using a clean installed Xubuntu Intrepid. Right after I rebooted with Chinese language support (with input methods, basic translations and additional fonts) installed, it became very slow again, but not as slow as the first time it had been. SCIM seemed to eat up all RAM and SWAP space. I took quite some time to undo the install, and the speed restored.

There's one thing that might be related. I had been annoyed with the double-SCIM-instance problem. Someone told me that I could modify the first line in /etc/scim/global (which is "/SupportedUnicodeLocales = en_US.UTF-8" by default) to use the desired locale so that only one instance of SCIM would be launched. It had worked before, but it could be the culprit here.

Another report with some new information.

However, what is the "the missing information" anyway?

Putting this under the scim package so wiser eyes can take a look.

In the meantime, can you try testing this issue on the newest release, Ubuntu 9.4 (Jaunty Jackalope). Thanks in advance.

affects: ubuntu → scim (Ubuntu)

Thank you for reporting. I think this may be fixed in 1.4.9 which is about to be released in Karmic. Please verify.
