[knot-dns-users] Upgrade broke journal

Hello, For the second time after an upgrade, one of my knot instance did not restart. (actually, it restarts but does not respond to queries) I got theses messages in log : 2017-03-27T17:11:16 warning: [durel.eu.] discontinuity in chages history (2017032310 -> 2017032309), dropping older changesets 2017-03-27T17:11:16 error: [durel.org.] zone event 'load' failed (invalid parameter) 2017-03-27T17:11:16 error: [durel.eu.] failed to store changes into journal (invalid parameter) 2017-03-27T17:11:16 error: [durel.eu.] zone event 'load' failed (invalid parameter) 2017-03-27T17:11:27 warning: [durel.eu.] discontinuity in chages history (2017032310 -> 2017032309), dropping older changesets 2017-03-27T17:11:27 error: [durel.eu.] failed to store changes into journal (invalid parameter) 2017-03-27T17:11:27 error: [durel.eu.] zone event 'load' failed (invalid parameter) 2017-03-27T17:11:27 warning: [durel.org.] discontinuity in chages history (2017032310 -> 2017032309), dropping older changesets 2017-03-27T17:11:27 error: [durel.org.] failed to store changes into journal (invalid parameter) 2017-03-27T17:11:27 error: [durel.org.] zone event 'load' failed (invalid parameter) removing all files in journal/ directory and restarting it leads to normal behaviour. Do you have hints about these error ? Thanks, -- Bastien Durel
