Hi Václav,

I can't estimate the implications of the docker usage on redis and intelmq.

Concerning the redis problem: There were no changes in the code handling redis problems and the only case when intelmq's bots do not log anything is when there are not enough resources to shutdown cleanly (memory, disk). Even then, there's output on stdout. You could log stdout and see if there are any errors shown at the end.

Concerning the error handling and sudden stops: There haven't been code changes too. Do you use the scheduled run mode? If the error_procedure is pass and there are pipeline problems, the bot stops (in bot.py search for "error_procedure: pass and pipeline problem"). AFAIR the reasoning for this was/is that if the bot would not stop, the pipeline would be kind of DOS'ed. But as problems with memory and snapshots in redis are handled better now, that could be relaxed. I'll do some experiments.

Concerning "encounters an exception and logs nothing but status check reports that the bot is not running": How do you know that the bot encountered an exception if nothing is logged? Is the bot then still running or not?

Hi,

no there are no modification to the intelmq code. The situation occurs at my custom bots as well as the default ones. As an example of this behaviour: recently Redis broker wasn't available for some time, as a result almost all bots stopped without any log message indicating that the bot stopped.

Sincerely,

Václav Brůžek

Hi,

I didn't know of any problems yet. Do you use any custom modifications in the code? If yes, which?

Hi,

since upgrading to version 1.1.0 it became quite a big problem the stability of bots. Often it happens that bot encounters an exception and logs that the bot is stopped or encounters an exception and logs nothing but status check reports that the bot is not running. I'm using the 'error_procedure' parameter set to 'pass' (with error_max_retries and error_retry_delay set to 0) and I've always thought that this is a sort of 'run forever' parameter that even when exception occurs the bot will keep on doing its job. I'm using intelmq in Docker environment with ubuntu 18.04 as base.

Sincerely,

Václav Brůžek
