[knot-resolver-users] stash failed, ret = 1

Hi, I just upgraded knot-resolver from 5.7.5 to 6.4.1 and now I'm seeing the following error message regularly: kresd[48937]: [cache ] [16128.01] stash failed, ret = 1 kresd[48937]: [cache ] [37316.01] stash failed, ret = 1 Can someone explain what that means? -- Stefan Schweizer
