0.14.6 seems to deadlock on file buffers #1258

shawnbutts · 2016-10-04T13:25:35Z

fluentd 0.14.6 (ruby 2.3.0).
Amazon Linux

All threads stop working. During the restarts I see one of these for each thread.

2016-10-04 13:20:06 +0000 [warn]: plugin_helper/thread.rb:74:ensure in block in thread_create: thread doesn't exit correctly (killed or other reason) plugin=Fluent::S3Output title=:enqueue_thread thread=#<Thread:0x000000025dc9e0@/usr/local/share/ruby/gems/2.3/gems/fluentd-0.14.6/lib/fluent/plugin_helper/thread.rb:58 aborting> error=nil

seems to be like #1010

Could you paste a entire log and sigdump result?

Hmm... it seems this error happens inside signal context.
We will investigate which mutex/lock causes this message.

shawnbutts · 2016-10-04T16:56:36Z

I've seen this with file buffer for forward_in, elasticsearch, and s3 plugins. Running with -v, everything runs fine for a while. But, then there is no further log output or activity for 10 minutes or more (should flush at least once a minute). After another 5 minutes of nothing and hitting a ctrl-c, the above is the output.

shawnbutts · 2016-10-04T18:43:57Z

Here is a the end of a trace log https://gist.github.com/shawnbutts/5219e076472242aa17d643e468938f77

After the last line of the log, it just stops doing anything.

repeatedly · 2016-10-04T18:55:29Z

Thanks for the detailed log.

@tagomoris Could you handle this?

tagomoris · 2016-10-05T08:14:30Z

I'm checking code, but couldn't find clear causes right now.
@shawnbutts Does the your problem occur every time? Could you paste your configuration?

shawnbutts · 2016-10-05T08:19:50Z

The more threads, the longer it takes. But, yes, it happens every time.
I've update the gist. The "startup.log" has the config, etc from the beginning of the log.

tagomoris · 2016-10-05T08:28:48Z

Thank you! I'm digging the situation further more.

tagomoris · 2016-10-05T12:29:45Z

I pushed a branch with fix for output thread handling in shutdown sequence.
https://github.com/fluent/fluentd/tree/wakeup-threads-in-shutdown-sequence-to-quit-sleep

I couldn't reproduce the exact same problem (deadlock detected) in my environment, but found some problematic log messages with fluent-plugin-s3 and Fluentd v0.14, and this branch has changes to solve it.

@shawnbutts Could you try this branch for your problem?

shawnbutts · 2016-10-06T18:14:18Z

Sorry, I wasn't able to test this. I've moved back to 0.12.x where this does not appear to be happening.

kkniffin · 2016-10-07T21:40:32Z

I think I may be having a similar issue. I upgraded to the latest release recently and now fluentd no longer seems to function. I continually receive buffer errors and nothing is output to Elasticsearch.

Here is my config:

@kkniffin it's just TRACE log to trace plugin's internal behavior, not to show any troubles or errors.

Yah, but it just constantly floods the screen and never actually sends any
information to elasticsearch. Rolling back the code produces none of those
trace errors and elasticsearch functionality works again.

Also I am not sure why it even is using that as I am not using buffering I
didn't think.

@kkniffin Trace log is for debugging and identifying problems. Filter them out on your environment not to send them to elasticsearch. It's not related with this issue.

I'm expecting that #1264 solves this problem, so let me close this.
Please reopen this or create another one for same/similar problems.
