[knot-dns-users] error: zone event 'journal flush' failed (not enough space provided)

Hi all, I would kindly ask for help. After a tiny zone record modification I am receiving following error(s) when trying to access zone data (zone-read): Aug 02 15:09:34 idunn knotd[779]: warning: [xxxxxxxx.] failed to update zone file (not enough space provided) Aug 02 15:09:34 idunn knotd[779]: error: [xxxxxxx.] zone event 'journal flush' failed (not enough space provided) There is a plenty of space on the server, I suppose it is related to journal and db. Many thanks in advance, it is quite important zone. KNOT 2.6.7-1+0~20180710153240.24+stretch~1.gbpfa6f52 BR Ales Rygl
