Now I open Bazaar Explorer and after a little while the "check paths: None" messages start appearing.

After an hour I have to kill the process because it was using 100%CPU.
I don't know what else I can add, but other co-workers work just fine with this config.

Please let me know if I can add some more information.
Thanks in advance.

Today when trying to figure out what could be the cause of the problem I remembered that I had a script running via crontab.
This script was changing some files owners and permissions inside the repo. After disabling this script, problem stopped. Is it possible that periodically changing permissions and owners can cause this behavior? Thanks in advance.

Bazaar will detect changes in permissions as it detect changes in file's
contents. I think it doesn't care about user and group information.

It is probably very very usefull if you can give us more information on
how the script was changing permissions. What files the script could
change, and what files it would not. Maybe if you help us to recreate
the problem, a fix could be planned sooner.

Hi dedeco,

Here's what the script does:

chown pablo:root /usr/local/scripts/ -R -L
chmod ug+rw /usr/local/scripts/dnw/ -R
chmod +r /usr/local/scripts/dnw/ -R
chmod o-w /usr/local/scripts/dnw/ -R

chown www-data:pablo /var/www/ -R -L
chmod ug+rw /var/www/dnw/ -R
chmod +r /var/www/dnw/ -R
chmod o-w /var/www/dnw/ -R

Where /usr/local/scripts/dnw is a symbolic link to the folder /home/pablo/bazaar/DENWAPBX/trunk/scripts/ (that's inside the repo), and /var/www/dnw is a symbolic link to the folder /home/pablo/bazaar/DENWAPBX/trunk/www/ (that's also inside the repo).

Let me know if you need any additional info.
Hope it helps.

Thanks for answering.
