  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

using strace, problem is clear :

[pid 21229] open("/var/spool/postfix/plesk/certs.db", O_RDWR) = 7
[pid 21229] flock(7, LOCK_EX
LOCKED

It's not seem normal that smtp fail during this process...
 
The only temporal way that we have found to solve problem, is to kill multiple keep-secured.php process to stop so masive renew, and with this, stop the postfix lock
