SymptomsBind service does not work correctly as it should. Parallels Plesk Panel does not add DNS records of the domain. Bind service can stop listening on port 53. Sometimes Bind service can hands and does not respond. The following errors can be found in event log:
could not listen on UDP socket: address in use
creating IPv4 interface Loopback Interface 1 failed; interface ignored
UDP client handler shutting down due to fatal receive error: host unreachable
ResolutionIt is necessary to update Bind to the version 9.7.1-P1. This version is compatible with Parallels Plesk Panel 9.x.
Please read the article #5542 about Bind update procedure.
