Hi Mark,

Which version did you migrate from?
10.1.30

How often do you see these messages?
Hardly ever, maybe a dozen of times ... we have millions of daily requests

Do they correlate with any particular (failed?) request.
No

I don't have more information, just these traces. The first trace 
(NullPointerException) is new, the second one (Warning) was also occurring in 
10.1.30

Best,
Joan.

Which version did you migrate from?

How often do you see these messages? Do they correlate with any particular 
(failed?) request.

That is odd. I wouldn't expect byteBuffer to be null at the end of a request.

Another odd one. I don't immediately see how that could happen either.

Any more information you can provided, particularly how to trigger 
either of these issues, would be appreciated.
