Plesk is slow, however, there are enough system resources on the server.
The following errors appear in
CONFIG_TEXT: ERR  Exception: Token validation failed: The license key 'PLSK.0000000' was not verified. Plesk will try to verify license key. Please wait for few minutes and try again. To manually run verification of license key click "Retrieve Keys" button in "License Management".
Pressing Retrieve Keys in Tools & Settings > Licence Management shows that the license is up-to-date.
grsecurity is used on a server.
/etc/sw/keys/instancesdirectory has permissions that differ from an example below:

drwxrws--- 2 root swkey-data 4096 Jun 2 2012 instances
Plesk keys registry file cannot be accessed. This is a Plesk bug with ID PPPM-6573 which was fixed in Plesk Onyx 17.8 micro-update 4.
Connect to the server via SSH.
Ensure that correct permissions are set for
# chmod 2770 /etc/sw/keys/
# chown root:swkey-data /etc/sw/keys/
If grsecurity is used, ensure that
psaadmis a member of
# usermod -a -G procread psaadm
Backup the file
# mv /etc/sw/keys/registry.xml /etc/sw/keys/registry.xml.bak
Regenerate the file by pressing Retrieve Keys in Tools & Settings > Licence Management.
Note: If it did not help, reinstall the license key at Plesk > Tools & Settings > Licence Management > Install Key .
