Dear all,
As I just found out, when using the integrated phpMyAdmin, session files are stored in /tmp (compared to /var/lib/php5 for "normal" webhosting sessions). At least for Ubuntu, this also means that these files will never be removed automatically.
I guess that /opt/psa/admin/conf/php.ini (which is used for the integrated phpMyAdmin installation) should be adapted to set session.save_path accordingly (currently, it is not explicitly set and thus pointing to /tmp).
