Re: [knot-dns-users] Knot 2.4.1 on CentOS 7

Hello, Since Knot 2.4.0 zone timers database is required (not optional). Could you purge the timers and confdb and start the server with the textual configuration only? Have you built the package with the embedded LMDB or is an external LMDB available? We know users running the latest Knot successfully. Daniel On 02/27/2017 10:32 AM, Abdulkareem H.
