Hi Brandon,
from the stacktrace it looks like client closes connection and when
server tries to write a data - we see the exception. Not sure it's a
problem on server side at all.
Is it possible to create a standalone testcase, which reproduces the
issue?
Once thing you can try - is to use SSLOutputWriter.flush(...) directly
instead of SSLAsyncWriteQueue, but as I told it may not help, cause
exception doesn't show any problem on server side.
Another thing, which may also help in investigation - is to set
"grizzly" logging level to FINE, this way we will have more info on
incoming SSL packets.
Thanks.
WBR,
Alexey.
