----------------------------------------------
Hi [~swd847],
We have this same issue occurring in one of our production servers. We have not be able to
reproduce this in our lab setup until now.
The direct buffer memory is filled up to 12gb(-Xmx) before we start to see the exceptions
in the logs.
Any help on reproducing this issue to check if the
https://github.com/xnio/xnio/commit/b30ac9dbeeab484f1b8a366944bba4c17357b816 fix works is
appreciated.
Thanks
OutOfMemory DirectByteBuffer XNIO
---------------------------------
Key: WFLY-4696
URL: https://issues.jboss.org/browse/WFLY-4696
Project: WildFly
Issue Type: Bug
Components: IO, Web (Undertow)
Affects Versions: 8.1.0.Final, 8.2.0.Final, 9.0.0.Final
Reporter: Carlos RodrÃguez Aguado
Assignee: Stuart Douglas
Priority: Blocker
Fix For: 10.0.0.CR1
Attachments: wfly9_0_0_final.mp4, wlfy.mp4
I get this errors constantly in my server when a web connection is interrupted from the
browser for instance:

And then, I think this errors lead to a OutOfMemory crash:
