There are several active admin sessions on localhost with address 127.0.0.1 in Tools & Settings > Sessions Management :
Does it mean that somebody else is logged on Plesk server?
This is an expected behavior as active localhost admin sessions are used during daily maintenance script. The process runs as Plesk administrator (
psaadm system user) and perform maintenance tasks.
Check that daily maintenance script is running at the moment:
# ps ax | grep DailyMaintainance
7317 pts/0 S+ 0:00 /usr/bin/sw-engine -c /usr/local/psa/admin/conf/php.ini /usr/local/psa/admin/plib/DailyMaintainance/script.php
7650 pts/0 S+ 0:00 /usr/bin/sw-engine -c /usr/local/psa/admin/conf/php.ini /usr/local/psa/admin/plib/DailyMaintainance/task-script.php ExecuteStatistics --period=daily
Additionally Plesk server writes messages to action log in Tools & Settings > Action Log automatically as admin when there are some automatic actions required.
For example, Plesk will log suspending subscription action if the customer overused available resources:
127.0.0.1 admin [2014-01-13 14:40:08] 'Domain's disk space limit reached' ('Domain Name': 'domain1.com' => 'domain1.com', 'Maximum Disk Space': '' => '1048576000')
127.0.0.1 admin [2014-01-13 14:40:11] 'Domain's disk space limit reached' ('Domain Name': 'domain2.com' => 'domain2.com', 'Maximum Disk Space': '' => '1048576000')
127.0.0.1 admin [2014-01-06 01:41:34] 'Update Domain Status' ('Domain Name': 'domain3.com' => 'domain3.com', 'Extended status of domain': 'active' => 'suspended', 'Status': '0' => '2')
