Logstash crash on windows under high volume

arizonawayfarer · November 19, 2015, 5:55pm

When logstash has eventlog inputs configured on systems that have a high volume of eventlog traffic it crashes after a relatively short period of time with the following dump:

Peak volume appears to be about 150 eventlog entries per second.

C:\logstash\bin>logstash agent -f logstash.conf

I had this issue in 1.5 as well, and honestly I'm a little surprised that it still exists.. it seems to be a pretty well reported issue?

Here's my logstash.conf:

input {
	eventlog {
		type => 'Win32-EventLog'
		logfile => 'System'
	}
	eventlog {
		type => 'Win32-EventLog'
		logfile => 'Application'
	}
	eventlog {
		type => 'Win32-EventLog'
		logfile => 'Security'
	}
}

filter {

}

output {
  elasticsearch { 
    hosts => ["host1", "host2"]
    index => "windowseventlog-%{+YYYY.MM.dd}"
  }
}

Have you analysed the heap dump at all?

Here's what Visual Studio has to say about the dump, unfortunately the full text is too long for a post here, so I've truncated the loaded modules:

Still crashes...

playing with memory settings now

UPDATE: Giving it 2 gigs seems to have done the trick.. stable now.. fingers crossed!

warkolm · November 21, 2015, 6:13am

Oh, you only had 1GB heap, that'd be why

arizonawayfarer · November 23, 2015, 4:00pm

I dunno.. I don't think it's a memory issue. I would have expected an out of memory error before the update and test I ran. Not to mention the other people having the same problem...

Also worth mentioning that when Java runs out of memory it writes a different type of dump.
