fluentd announcement

Hi users!

We have released v1.16.5 on 2024-03-27. ChangeLog is here.

The previous version v1.16.4 has a serious Buffer bug when it processes large data exceeding chunk size limit. So, we have released v1.16.5 urgently, and have fixed the bug. So, please don't use v1.16.4.

Sorry for troubling.

Bug Fixes

Buffer: Fix emit error of v1.16.4 sometimes failing to process large data exceeding chunk size limit

In the previous version v1.16.4, we fixed a Buffer bug (Please see Fluentd v1.16.4 has been released for details).

There was a race condition problem with that fix, and similar Buffer errors explained in Fluentd v1.16.4 has been released could occur.

emit transaction failed: ...
send an error event stream to @ERROR: ...

These errors are the same as the Buffer error of Fluentd v1.16.4 has been released, but it would be more likely to happen. The cause is a race condition when processing large data exceeding chunk size limit. So, in that case, these errors can occur depending on the timing.

So, please don't use v1.16.4.

See #4447 for more information.

Sorry for troubling.
