<p>Hi Václav,</p>
<p>I can't estimate the implications of the docker usage on redis
and intelmq.</p>
<p>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.</p>
<p>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.</p>
<p>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?</p>

<div>no there are no modification to the intelmq code. The
situation occurs at my custom bots as well as the default

wasn't available for some time, as a result almost all bots

<div dir="ltr">Hi,
<div>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.</div>
