Wildfly 10 XNIO XNIO001007 NullPointerException unexplained
Dear all
A migrated our applications from JBoss 4 to Wildfly 9, and 10 recently.
No problem at all, except on one site having more then 500 clients.
After some days running well, we encounter this exception.
I found some similar topics in the furum, but the cases do not fit, and I have no idea where to dig.
