Filebeat 32-bit crash in Windows environment

It seems the filebeat I installed in Window environment keep crashing before send any log files into logstash.

currently I am using filebeat version 1.1.1 and later tested with 1.2.3 however the results are the same.

Here is the my config file:

  # List of prospectors to fetch data.
        - "//test/temp/Spark/27/*.log"
        - "//test/temp/Spark/28/*.log"
      input_type: log
      encoding: utf-8
        pattern: "Time of Log: [[:digit:]]{1,2}/[[:digit:]]{1,2}/[[:digit:]]{4}"
        negate: true
        match: after

And output from my debug window captured this:

Could anyone please give me some hints for how to fix it.


panic happens when allocating memory from OS fails. I think we've seen this on 32bit versions.

The sysReserve call already fails returning a NULL-pointer. Checking the golang runtime code a NULL-pointer check has been introduced in go1.6. But even with newer go runtime version this still would fail, as runtime fails to reserve some virtual address space from OS.

Can you run filebeat 1.2.3 with -e -v -d "*" and post the log output here? I wonder if this will look different. Please use </>-button to format logs, config files and code to make it somewhat readable.

Thanks Steffens.

I run filebeat 1.2.3 this morning and here is the result of crashes(only a few lines at the beginning of the crashes.)

Just an update of my issues.

I tried to use Filebeat 5.0.0-alpha5 (Windows 64 bits version) without any change of the config file, it all works fine!

It looks current filebeat production Windows version 1.2.3 also has this issue, it happens when trying to parse over certain amount of files, in my case it's over 300 files, and each event have multiple lines(some of my event over than 1000 lines). My filebeat version seems to crash and failed on allocate memory under Windows Server 2012 R2.

It seems Filebeat 5.0.0-alpha5 (Windows 64 bits version) has solved the problem.


yeah, 64bit binaries should help. Problem might be 32bit runtime trying to allocate more continuous virtual memory as supported by default on windows:

see error messages:

fatal error: runtime: cannot map pages in arena address space

this is virtual alloc reserving some address space for potential use, this is not about real memory being used.

For reference VirtualAlloc with MEM_COMMIT and PAGE_READWRITE fails.

I think you are right Seffens,

Have read the thread here:

I believe the issue is due to the max amount of files opening in file beat windows 32 bit version. In our case one log folder contains 11337 files and another log folder contains 29911 files. For the first-time parse this is an issue due to Window memory allocation failure with max threads exceed single process handling limit in Win 32 bits filebeat version.

It seems the 64 bits version has this issue fixed and our team decided to give it a go and see how it's going.

Would like to hear from ELK team how this issue get fixed in 64 bits version and when the production version of 64 bits could be released in a near future.


The 64bit version doesn't really behave different. The difference is with windows treating 32bit and 64bit binaries differently and applying other limits.

You have an estimate about number of files being handled concurrently (number of files open by filebeat)? Setting close_older to a few minutes will ensure filebeat closes files earlier.

Filebeat does not limit number of open files yet, as it is normally supposed to be a limited resource by the OS. Once out of available file-descriptors filebeat will just try and wait for resources being freed and continue processing.

Filebeat 5.0 will be released same date as elasticsearch, logstash, kibana 5.0. But I have no exact date for you yet.

Setting up a golang development environment you can rebuild filebeat 1.2 for 64bit windows yourself I think. But Filebeat has advanced this much since 1.x, personally I would prefer users going with current 5.0 alpha release then 1.x release. New beta phase (basically feature freeze) might start soonish (I hope, no actual date).
