Symptoms
The Dr.Web license does not automatically update. When I try to manually update it, the following error is shown:
Unable to assign the license key 'PLSK012345678910' to the node 'apache.example.com': Another 'drweb-unix' license key is already assigned to the node 'apache.example.com'.
Cause
This behavior is caused by software issue #PPA-474. The fix is included in MU #7.
Resolution
Update PA to the latest version:
/usr/local/ppa/bin/ppa_update --install-updates
