Description John Eckersberg 2016-03-30 21:26:23 UTC

Starting with erlang-erts-R16B-03.10min.6.el7ost.x86_64, the log handler repeatedly crashes and fills up the rabbitmq startup_log with entries like:

Event crashed log handler:
{info_msg,<0.1719.0>,
          {<0.1832.0>,"Mirrored ~s: Adding mirror on node ~p: ~p~n",
           ["queue 'l3_agent_fanout_0f6bc20f4c54484f9de482cd6d83a15a' in vhost '/'",
            'rabbit@overcloud-controller-1',<6192.10668.1>]}}
function_clause

Meanwhile the rabbitmq log is empty.

Looks like a regression introduced in the "Enable error_logger depth fine tuning" patch.

Comment 3 Alexey Lebedeff 2016-04-07 13:17:10 UTC

R16B-03.16.el7 is also affected.

Comment 4 Asaf Hirshberg 2016-04-10 14:53:42 UTC

I update my environment to 08/04 puddle but couldn't find erlang-R16B-03.10min.9.el7ost, where can I get it or it should be in the latest puddle?

Comment 5 Jon Schlueter 2016-04-11 12:53:20 UTC

moved back to modified as not part of a puddle yet.

Comment 7 John Eckersberg 2016-04-11 20:11:05 UTC

Looks like it's in puddle 2016-04-11.1 now

Comment 8 Asaf Hirshberg 2016-04-12 12:38:56 UTC

Verified using 2016-04-11 puddle.

Comment 11 xiaoxwan 2016-08-31 02:54:31 UTC

Hi, I'm here to ask a question. Well it might be stupid.
This bug starting with:
    erlang-erts-R16B-03.10min.6.el7ost.x86_64 (by Description)
Fixed In Version:
    erlang-R16B-03.10min.9.el7ost
And by checking the changelog, if this "Looks like a regression introduced in the "Enable error_logger depth fine tuning" patch."(by Description) is the reason, then both "erlang-erts-R16B-03.10min.9.el7ost.x86_64" and "erlang-R16B-03.10min.9.el7ost" got this bug fixed.
So I am wondering that what's the connection between erlang and erlang-erts?
Why not just say "fixed in version:erlang-erts-R16B-03.10min.9.el7ost"?
Could anyone give me a hand?

erlang-erts is just a subpackage of the main erlang package.  Typically one only refers to the main package when referencing builds in the build system and errata tooling.
