Hello, I fixed my problem. strace indicated a problem with netdata's sqlite database. That was not reported in any netdata output. So I deleted the contents of /var/cache/netdata and all was fine.
So while my problem is solved, there might be two problems that caused this bug report: - sqlite conversion seems to be faulty. At least that's what the strace output suggests. I attached it for completeness and maybe an upstream bug report. - `apt purge netdata` should delete or offer to delete /var/cache/netdata. If it would have done that, my problem would have been fixed quite soon: [gru:~] % apt purge netdata Reading package lists... Done Building dependency tree... Done Reading state information...
