- Plesk Onyx for Linux
plesk repair webcommand takes a lot of time to finish (several hours);
- A large number of domains are being hosted on the Plesk server (e.g. 1000+ domains);
- Fail2Ban is installed on the Plesk server.
Fail2Ban takes a long time to restart when a large number of domains are hosted.
This is Plesk bug with ID #PPPM-8907 which will be fixed in future Plesk updates.
There is currently no workaround for this issue.
