Logstash pipeline stalling without any error

Stephy · October 21, 2021, 8:35am

Hello,
We have a Logstash pipeline (using the official elastic.co Docker Image v7.9.3) running with a JDBC input plugin and Elasticsearch output. Pipeline is set to run with a schedule every 1 minute (* * * * *). The input plugin fetches data from a Oracle DB via a select statement.
Logstash version used: 7.9.3
Elasticsearch version used: 7.9.3

Config: 
input {
  jdbc {
    jdbc_driver_library => "/usr/share/logstash/driver/ojdbc8.jar"
    jdbc_driver_class => "Java::oracle.jdbc.driver.OracleDriver"
    jdbc_connection_string => ""
    jdbc_user => ""
    jdbc_password => ""
    jdbc_fetch_size => 1000
    statement => 'select * from [TABLE] WHERE ("[TIMESTAMP COLUMN]" IS NOT NULL) AND ("[TIMESTAMP COLUMN]" > :sql_last_value)'
    tracking_column => [TIMESTAMP COLUMN]
    tracking_column_type => "timestamp"
    record_last_run => true
    schedule => "* * * * *"
    last_run_metadata_path => "/usr/share/logstash/config/lastrun/[FILENAME].yml"
 }
}

Problem: This is running fine for days, even weeks. However, at some time, seemingly random, the SQL statement is not executed any longer. This means new data is not indexed.

So sometimes the pipeline suddenly stops executing/stalls until restarted, the timestamp for the last_run doesn’t get updated but the container stays up and the Logstash pipeline is running. We are still able to exec into the container and verify that Java processes are running. Elasticsearch is also running.

Evidence: The last logs that we have in the pipeline is DEBUG and as follows:
Note that these logs are not from when the error occurred (we couldn’t get the logs for the error as they were much older) but these logs keep appearing again and again after

Hey,

Could you manage to find older logs or reproduce this ?

Really tough to know what is happening here.

Hello, @grumo35 thanks for the quick response!

As we said earlier we didn't have the logs for the time when the error occured, but it happened again and we managed to get the logs and they are as follows:

It looks like the shutdown() is used in the last moments, i honestly think you'll have to get some help other than me

Looks like Debug log aren't worth a lot, are you on linux ? can you manage to setup some advanced debug using somethinkg like jstack or strace/ptrace ?

Your input is configured to run once a minute. The last run completed at 22:32:00.380394, which means it took less than half a second to complete.

At 22:33:00,432 the inputs starts its next run. It takes 14 seconds to get as far as executing the COUNT version of the query, and another 14 seconds before it actually tries to run the query itself. It takes 70 times as long as the previous run. It then processes the result and indexes it a tenth of a second later.

At first I thought it might be endless stop-the-world mark and re-mark phases in the ConcurrentMarkSweep GC, but that doesn't feel right.

I agree that you need to find out what the JVM is doing if it is not running the file input. A thread dump would be the place to start.

Hello , @Badger @grumo35

As requested, we have a full thread dump in the link(some repetitive passages have been removed for better readability) : https://drive.google.com/file/d/1-dUTkriXPGE23JPTNtwHJ4e1yH5I8d8l/view?usp=sharing

There are some excerpts from the dump which we suspect might be the cause but still doubtful and are as follows:

I think this is the jdbc input. It is parked, waiting for something.

This is a thread waiting on Oracle. I have a feeling the problem may be in the database rather than logstash, although if restarting logstash clears the issue I am not sure how the problem could be in Oracle.
