I ran winlogbeat-5.0.0-alpha1-windows-32 on windows server 2003 R2 SP2 32bit and encountered some error,
need your verification. thanks.

but also I find a workaround:that is to clean all the eventlog(applications,security,system),then it works to start winlogbeat~:grinning:
is that overmany logs exceed the Max Bulk Size of winlogbeat? (just my guess based above log,need your analysis).
Thanks for reporting it. I think the issue is that it was trying to read an event log record with a larger than usual message size. And this exposes an issue with the buffer sizing. It is not related to max bulk size.
I will write up a test case to confirm my suspicion next week and get back to you.
I also have this issue (It's why I tried to filter by eventID).
Here are the last couple DBG lines of -e -d "*" and the panic lines. I hope it helps.

@Alreanaes Thanks for reporting the issue. It looks like it's probably a similar bug, but in code for the newer Windows event log API. I'll work on a test case to reproduce it and keep you updated here. UPDATE: I opened PR for this issue too: https://github.com/elastic/beats/pull/1499
