Hello.

I know, this problem regards to the OpenOffice forums, but...not necessarily...
I've very weird problem:
Sometimes, my OOo locks. When I try to start soffice, swriter.... I
can't: some seconds mixing my HDD and silence.
Well. I change the user id (UID) to different - it's start normally.
But, when I try the previous UID - I can't start OOo again.
I've locked 2 UIDs from OOo. It's good to have lot of UIDs into the
linux, but it isn't the good way to change every time UIDs to start OOo.

Any suggestion?

I don't understand what you mean by having a lot of user id's. If you create a new user, on the other hand, and this user doesn't have the same problems, then it sounds like your configurations are mucked up somehow.

Simply changing your UID could cause problems because your own files will have permissions for another user. If you've been doing this, changing your UID without using chown on all your personal ooo configuration files could be the reason that ooo is locking up for you.

You might look at the ownership and permissions of all of the files in $HOME/.ooo-2.0-pre/

...
OK. Step by step:
- ex. I've UID=1000, I can't start any progs from OOo
- I change UID to 1001, chown -R on my /home/user dirs and files, OOs starts normaly...
- after some days (sometime weeks, months...) on UID=1001 , my OOo crashes again, no chance to start any apps from OOo
- I change to UID=1003, no problems, OOs starts again
- But , when I can change UIDs to previously used (1000, 1001) to check, that is OK or NOT, my system remembers the blockage of OOo
- root can starts every apps from OOo without problem, but I use root's account not sporadic, (I use sudo su on normal accounts). But when my system will do this on UID=0 (it's possible), what will be next UID for root ?
- I haven't any messages when I start apps from OOo under X
- No infos in logs...
It isn't the problem with permissions on folders, because I chowned OOo dirs to ex. user.users, all libs into usr, kde too.

Anywhere, my system holds information what are relations between OOo and UIDs..., the question is: where...

I would recommend creating a new user and logging in as that user. Then compare the configurations for ~/.ooo-2.0-pre/ for both users. Also check for differences in ~/.kde that might account for the reasong OpenOffice doesn't start.

Also, start OpenOffice from the shell and note any messages that come up. Try to determine the reason that it doesn't start and fix that.

When you changed your UID, you probably didn't catch all of your user files, such as in /var/tmp/, /tmp/, and the mail cache. These items were then created anew after you changed your UID.

You might also consider logging off, log in as root in the console (init level 3 -- no x windows) and clear out any /tmp files owned by your user name(s). Maybe even clear out /var/tmp/ files that you own also. This might clear out a lot of garbage. Also clear out files owned by your old UIDs:

Using the find command can help locate these files, for example finding your old uid=1000 files and your current ones if your user name is "marekjs"
find /tmp -uid 1000"
find /tmp -user marekjs
