[undertow-dev] AS7 Subsystem - OutOfMemoryError: Direct buffer memory

[Darran Lofthouse]

Hello all,

Making use of the subsystem integration for Undertow I am getting the 
error at the bottom of this message each time a request is received by 
the server.

I am using Fedora 17 (About to move to 18) but I know quite a few 
engineers are on OSX so just wanted to check if anyone else is 
experiencing this on other operating systems?  Or is it just mine? ;-)

I should add this is a cleanly built AS7/master, Undertow/master, 
Undertow-Subsystem/master, AS7 started using standalone-undertow.xml and 
one simple war deployed - no other changes have been made anywhere.

Regards,
Darran Lofthouse.
