Every time daily maintenance task is being executed service PSA stops.
'/var/logs/sw-cp-server/error_log' you may see the message like the following:
2014-01-28 03:31:23: (server.c.1543) server stopped by UID = 0 PID = 675006
During execution of Daily Maintenance task Plesk autoinstaller fails to upgrade
psa-mod_fcgid package because 3rd-party
mod_fcgid package is already installed. This package holds the configuration file
'/etc/httpd/conf.d/fcgid.conf' and does not allow to install the package of an older version.
# rpm -qa | grep mod_fcgid psa-mod_fcgid-2.3.6-12050315.x86_64 mod_fcgid-2.3.9-1.el6.cloudlinux.x86_64
Remove such package:
rpm -e mod_fcgid-2.3.9-1.el6.cloudlinux.x86_64 --noscripts --nodeps --justdb
Complete upgrade Plesk components:
#/usr/local/psa/admin/bin/autoinstaller --select-product-id plesk --select-release-current --upgrade-installed-components
