----------------------------------------------
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
