Question

Hi,I encountered a problem with cache.db. I've set

chown -R apache:apache /var/www/twiki

[abc@xyz LdapContrib]$ pwd
/var/www/twiki/pub/_work_areas/LdapContrib
[abc@xyz LdapContrib]$ ls -l
total 1124 -rw-r--r-- 1 root root 1396736 Apr 30 11:00 cache.db

Software error:
Cannot open file /var/www/twiki/pub/_work_areas/LdapContrib/cache.db: Permission denied at /var/www/twiki/lib/TWiki/Contrib/LdapContrib.pm line 543.
For help, please send mail to the webmaster (root@localhost), giving this error message and the time and date of the error. 

I chown of cache.db to apache,but over a period of time,it's owner turned to be "root" again.

I guess a setting for email notification in /etc/crontab may affect this issue,because I received email from /var/spool/mail/root

Subject: Cron <root@localhost> perl -I /var/www/twiki/bin /var/www/twiki/tools/mailnotify 
........
constructed a new LdapContrib object
cacheAge=86978, lastUpdate=1245687855, refresh=1
updating cache
called refreshCache
called refreshUsersCache()
found 500 entries
.....
........................

I don't know why the owner of cache.db changed to be root and cause the error in browser.

Please help if you can,thanks in advance!

Maybe caused by crontab,change owner to apache

Better don't run any TWiki cronjobs as root, last but not least for security reasons. Remove this line from /etc/crontab and add it to the one of the user apache to make sure it is run as apache, not root
